Russian President Vladimir Putin told an audience Tuesday that Russia was going through "difficult times" as its invasion of Ukraine continues, but said national pride was growing.
"Yes, Russia is going through difficult times now; things have never been easy, but, still, today we are seeing a moment of our common consolidation, with our national pride being sharpened," Putin told an awards ceremony, according to comments reported by state news agency Tass.
Elsewhere, the Kremlin said Wednesday that it's premature to talk about a peaceful settlement, with Putin's press secretary Dmitry Peskov saying the preconditions for an end to the conflict did not yet exist.

When asked by reporters which peace proposals were closest to Russia's position, Peskov said:
"It is premature to talk about this as long as there are no prerequisites for a peaceful settlement. The special military operation continues," as Russia calls its unprovoked invasion of its neighbor.

"It's completely just irresponsible and unacceptable that they've decided to now extend his detention another three months here while they work through their quote, unquote, judicial process. He needs to be released. He's not a criminal. He's a journalist. We want him home," National security council spokesman John Kirby said on a call with reporters.
"We're going to continue to a seek consular access to him, which they have denied us a second visit and be continued to explore options to see what we can do to negotiate to get him released and get him home where he belongs," he said, adding that the Biden administration is also working for the release of Paul Whelan.
Whelan, a former Marine, was arrested by Russian authorities in 2018 on espionage charges. At the time he was arrested, Whelan was visiting Moscow to attend a wedding, according to his brother, David Whelan.
Whelan was convicted in 2020 and sentenced to 16 years of hard labor in a Russian camp in the remote province of Mordovia.

Russia says warship guarding Black Sea pipelines was attacked by Ukraine
A Russian warship stationed in the Black Sea was attacked in the early morning by multiple unmanned Ukrainian speedboats, Russia's Defence Ministry said, according to Reuters.
The ministry said in a post on Telegram that the warship Ivan Hurs was protecting the TurkStream and Blue Stream gas pipelines and "continues to fulfil its tasks," Reuters reported.
Last week Russia agreed to extend the Black Sea Grain Initiative, allowing Ukraine to safely export grain in the Black Sea.
Kyiv did not immediately respond to the report, and CNBC wasn't able to immediately verify the authenticity of the footage.

Wall Street Journal calls for immediate release of Evan Gershkovich following extension of pre-trial detention
The Wall Street Journal has reiterated calls for Evan Gershkovich's release from a Russian prison, following a court decision to extend his pretrial detention for three additional months.
Gershkovich, a reporter based in Moscow, was arrested in March by Russian authorities on espionage charges.
"While we expected there would be no change to Evan's wrongful detention, we are deeply disappointed. The accusations are demonstrably false, and we continue to demand his immediate release," The Wall Street Journal wrote in a statement.
The Biden administration and the Journal have repeatedly denied Russian allegations that Gershkovich operated as a spy in Russia.

U.S. distances itself from pro-Ukraine incursion into Russia that involved American equipment
The United States has sought to distance itself from an alleged cross-border raid into Russian territory by pro-Ukraine fighters who appeared to use American equipment in their attack, NBC News reported.
While much is unclear about the fighting, Moscow said Tuesday it fought off an assault in its Belgorod region conducted by saboteurs from the Ukrainian military. Ukraine has said it was carried out by Russian citizens who rose up independently, according to NBC News.
The Russian Volunteer Corps, which claims to be made up of Russians fighting on behalf of Ukraine, posted video Wednesday morning showing it was in possession of Mine-Resistant Ambush Protected, or MRAP, vehicles although it was unclear where it was filmed.
Asked about the images, U.S. officials told NBC News they were monitoring the reports and added that the U.S. has not authorized Ukraine to give the equipment to anyone else and that Ukraine has not asked for the right to do so.

Ukraine's defense minister meets with British counterpart in Kyiv
Ukraine's Defense Minister Oleksii Reznikov thanked his British counterpart on Twitter for visiting Kyiv.
"We had a very meaningful discussion focused on priorities for increasing Ukraine's defense capabilities, particularly providing long-range weapons such as Storm Shadow," Reznikov wrote on Twitter, referencing the U.K.-made air-launched cruise missile.
Reznikov added that the two also discussed the prospect of Ukraine's ascension to the NATO military alliance.

No ships have sailed under Black Sea grain deal in the past five days
In the past five days, no ships have left Ukrainian ports under the Black Sea Grain Initiative, according to the latest figures provided by the U.N.-backed organization tracking the export activity.
The Black Sea grain deal, which reopened three Ukrainian ports and established a humanitarian sea corridor for agricultural exports, was extended last week.
The last ship to sail under the agreement carried 6,800 metric tons of wheat and departed Ukraine's port of Chornomorsk for Italy on May 19.

Ukraine says Russia is continuing to 'militarize' Zaporizhzhia nuclear power plant
Ukraine's defense ministry said Russia is continuing to "militarize" the Zaporizhzhia nuclear power plant occupied by Russian forces in southern Ukraine.
"Currently, the territory of power units No. 1, 2, 4 is actually used as a logistics and military base," the defense ministry said in a statement Wednesday, repeating previous accusations that Ukraine has leveled at Russia, accusing it of using the nuclear plant as a military base. Russia has previously denied the claims.
The defense ministry said that firefighters, armored vehicles and trucks are stationed at the nuclear facility, Europe's largest, permanently but that the number of vehicles and military personnel is constantly changing.
"Five to 20 pieces of equipment can be near each power unit during one day. The rotation takes place covertly during the curfew (from 11 p.m. to 5 a.m.). All trucks are tightly sealed. There is information that they may contain ammunition and explosives," the ministry noted, without providing further detail.
The ZNPP has frequently found itself at the center of hostilities in the war and earlier this week the plant suffered its seventh emergency power outage since the start of the invasion, forcing the plant to rely on diesel generators to power core cooling systems.

Russia will react 'extremely harshly' to further attacks, defense minister says
Russia will react "extremely harshly" to further attacks by fighters entering its territory from Ukraine, Defense Minister Sergei Shoigu said on Wednesday.
The Russian military said on Tuesday it had routed militants who attacked a Russian border region with armored vehicles the previous day, killing more than 70 "Ukrainian nationalists" and pushing the remainder back into Ukraine.
"We will continue to respond to such actions by Ukrainian militants promptly and extremely harshly," Shoigu told defense ministry officials, in remarks published by the ministry.

Russia's leadership blames the West for creating instability and rising tensions
Russian President Vladimir Putin and Moscow's top diplomat Sergey Lavrov both blamed the West for creating global insecurity and instability.
As Russia's invasion of Ukraine continues, Putin said Wednesday that the world was becoming increasingly unstable and that "new centers of tension are emerging."
Speaking at a high-level meeting in Russia on security issues, Putin said rising instability was due to individual countries and associations trying "to preserve, retain their dominance, impose their own rules, completely ignoring the sovereignty, national interests, traditions of other states."
"All this is accompanied by a buildup of military potential, unceremonious interference in the internal affairs of other countries," he said, "as well as attempts to extract unilateral advantages from the energy and food crises provoked by a number of Western states."
Speaking at the same event, Lavrov, Russia's foreign minister, said the West wanted to inflict a strategic defeat on Russia and claimed NATO weapons for Ukraine were being spread beyond the country's borders.
"The collective West does not hide its intention to inflict a strategic defeat on us. The Kyiv regime is being used as an anti-Russian battering ram, which is being pumped up with NATO weapons. At the same time, part of the Western supplies — and an increasing part — are spreading uncontrollably around the world," he said, according to a Tass news agency report.
Russia invaded Ukraine 15 months ago in a bid to overthrow the pro-Western government in Kyiv and regain its influence over the former Soviet republic. Western countries rallied around Ukraine to provide it with military and financial aid to help it defend itself against its neighbor.

Russia says the 'peak of anxiety' has passed in Bakhmut; Ukraine fights on
A pro-Russian official in the Donetsk region of Ukraine said Wednesday that the "peak of anxiety" had passed in Bakhmut, a town Russian mercenary forces claimed to have captured last weekend.
"The peak of anxiety, when there was the most active phase, the enemy tried to surround the guys on the flanks in Artemovsk itself, has passed," said Denis Pushilin, the Moscow-installed acting leader of Donetsk, a region in eastern Ukraine that's partially occupied by Russian forces, using the Soviet-era name for Bakhmut.
"I think that the risk is minimized but, of course, it exists, because the enemy can throw some more reserves," Pushilin said, according to Russian news agency RIA Novosti.
Russia's Wagner Group of mercenary fighters claimed to have fully captured Bakhmut last weekend after nine months of intense fighting with Ukrainian forces over the town.
Ukraine denied the claim, however, saying it still occupied southwestern peripheral parts of the city and that its forces were advancing on the flanks of the city in a bid to encircle Russian forces there.
The battle for Bakhmut has become highly symbolic rather than strategic, with Kyiv reluctant to abandon the town. Ukraine's military said Wednesday that Bakhmut continues to be at the epicenter of fighting in the wider Donetsk and that Russian forces had conducted unsuccessful operations to the west of the town.

Is the West losing in its bid to reduce demand for Russian oil?
Russia's oil revenues rebounded in March and April to reach the highest level since November last year, according to a new report, bolstering President Vladimir Putin's ability to finance the Kremlin's onslaught in Ukraine.
Analysis published Wednesday by the Centre for Research in Energy and Clean Air, an independent Finnish think tank, found that Russia's revenues from oil exports have recovered from levels reached in January and February.
The findings show that Moscow has recently been able to successfully claw back earnings from fossil fuel exports despite the imposition late last year of import bans from the European Union and a broader Group of Seven oil-price cap.
It comes less than a week after G7 leaders said at the conclusion of the summit in Hiroshima, Japan, that a price cap on Russian oil and petroleum products was working, Russian revenues were down and falling oil and gas prices were benefiting countries around the world.

Putin says Russia is going through 'difficult times'
Russian President Vladimir Putin told an audience Tuesday that Russia was going through "difficult times" as its invasion of Ukraine continues, but said national pride was growing.
"Yes, Russia is going through difficult times now; things have never been easy, but, still, today we are seeing a moment of our common consolidation, with our national pride being sharpened," Putin told an awards ceremony Tuesday, according to comments reported by state news agency Tass.
Putin said Russia was "striving at all costs to strengthen the foundations of our spirituality, to create the conditions in the economy, manufacturing, and education of our young people in order to ensure the unconditional future of our country."
He said Russia had become more self-sufficient in recent years, although he did not cite international sanctions as a reason for this.
"We have become much more self-sufficient. Without self-sufficiency, there can be no sovereignty, and self-sufficiency is being achieved in all areas: in art, in science, in industry and, of course, in the military," Putin said.
Russian officials have frequently tried to find a bright side of the many international sanctions that have been imposed on the country following its invasion of Ukraine, as well as for earlier misconduct, ranging from 2016 U.S. election interference to the nerve agent poisoning of a former spy in the United Kingdom.
Russia's invasion has caused mass destruction in Ukraine and the deaths of thousands of civilians (the U.N. estimates the number at almost 9,000, although the real number is likely to be far higher) and possibly several hundred thousand deaths among soldiers on both sides.

There are no conditions for peace in Ukraine, Kremlin says
The Kremlin said Wednesday that it's premature to talk about a peaceful settlement of the conflict in Ukraine, with President Vladimir Putin's Press Secretary Dmitry Peskov saying the preconditions for an end to the conflict did not yet exist.
When asked by reporters which peace proposals were closest to Russia's position, Peskov said:
"It is premature to talk about this as long as there are no prerequisites for a peaceful settlement. The special military operation continues," he said in comments reported by Russian state news agency Tass.
Russia's "special military operation," as it calls its invasion of Ukraine, would be accomplished, Peskov added.
"Russia is taking under consideration only the completion of its special military operation: ensuring its interests, achieving Russia's goals either through the special military operation, or by other available means."
When asked to clarify whether the Kremlin was ready for negotiations with their counterparts in Kyiv, Peskov said, "It is unlikely that this can be discussed, because any negotiations with the Russian Federation are prohibited [in Ukraine]."
Ukrainian President Volodymyr Zelenskyy said last year that Kyiv would not negotiate with Russia while Putin was in office.
Both Russia and Ukraine have "red lines" that they say they will not cross when it comes to any possible, future peace deal. Kyiv says Russia must remove all of its troops from occupied areas and says it wants all of its territory returned, including Crimea, annexed by Russia in 2014.
Moscow wants all Ukrainian regions it has annexed illegally to be recognized as Russian territory and wants guarantees Ukraine won't join NATO. On this latter point, there may be room for compromise, Ukraine said, if it can receive security guarantees from its international allies.

Russia and China are in an 'alignment of convenience,' not a 'deep alliance,' says professor
Russia and China are in an "alignment of convenience" — not a deep alliance that will "last 10 or 20 years," said Joseph Nye, Harvard University distinguished service professor emeritus.
Both countries see the U.S. as a "common irritant" rather than a "common enemy," Nye told CNBC's "Squawk Box Asia."
China has positioned itself as a peace broker for the war in Ukraine, sending representatives to Russia, Ukraine and other European countries last week in an attempt to set up negotiations. It released a 12-point peace plan in February calling for a de-escalation of the war.
The peace plan is not realistic because "the Chinese don't want to irritate the Russians," Nye said. But if Ukraine's planned spring offensive achieves a degree of success, Putin may feel that a cease-fire makes sense and China might "press him to accept" something more serious, Nye explained.
Beijing wants to "pose as the peacemaker" to regain its position in Europe, the professor said. "China cares about its soft power, its attractiveness in Europe, and it's lost a good deal through the strong support of Russia's invasion of Ukraine."
But to reduce its reputational damage, he added, China will have to "push Russia a little bit harder."

Ukraine says it's working to remove Russian troops from Zaporizhzhia nuclear power plant
Ukraine Prime Minister Denys Shmyhal said on his official Telegram channel that Kyiv is working to remove Russian forces from the Zaporizhzhia nuclear power plant.
"We are working with all our partners to force Russia to leave the ZNPP and create a demilitarized zone around the plant," according to an NBC News translation.
The nuclear facility, Europe's largest, was seized by Russian forces in the weeks following Russia's full-scale invasion.
The International Atomic Energy Agency, or IAEA, has previously called on Russia and Ukraine to create a demilitarized zone around the facility in order to mitigate a nuclear disaster.

'The more weapons are supplied, the more dangerous the world will be,' Kremlin says of Western support for Ukraine
The Kremlin placed blame on Western governments providing Ukraine with weapons, saying it's contributing to global security instability.
"The more weapons are supplied, the more dangerous the world will be," Dmitry Medvedev, deputy chief of the Russian Security Council, told reporters, according to a TASS report.
"The more destructive these weapons are, the more likely the scenario of what is commonly called a nuclear apocalypse becomes," he added.
Over the weekend, the Biden administration announced its 38th weapons package for Ukraine worth approximately $375 million.

The embassy also called for regular consular access to Gershkovich, adding that so far there have been two attempts that were denied.
The most recent incident came last week.
"We reiterate that the claims against him are baseless and call for Mr. Gershkovich's immediate release," the U.S. Embassy in Moscow wrote in a statement.

Russian court extends detention of Wall Street Journal reporter by three months
A Russian court decided to extend Wall Street Journal reporter Evan Gershkovich's detention by three months, according to a report from NBC News in Moscow.
Gershkovich, a reporter based in Moscow, was arrested in March by Russian authorities on espionage charges.
The decision from the Lefortovsky District Court of Moscow comes on the heels of a request by Russia's Federal Security Service, or FSB, to keep Gershkovich detained.
The Biden administration and The Wall Street Journal deny Russian allegations that Gershkovich was operating as a spy in Russia.

Hungary's Orban says Ukraine cannot win war, calls on Washington to find solution
Hungary's Prime Minister Viktor Orban spoke out against continued fighting in Ukraine, claiming that Ukraine itself cannot win the war and that the West needs to step in to end the conflict.
"Looking at the reality, looking at the figures, looking at the surroundings, looking at the fact that NATO is not ready to send troops, it's obvious that there is no victory for poor Ukrainians on the battlefield," Orban said during the Qatar Economic Forum.
"That's my position ... Escalation should be stopped and we should argue in favor of peace and negotiations." He added that the war was the result of a "failure of diplomacy."
The right-wing, populist Orban is on good terms with Russian President Vladimir Putin and has not directly condemned him for Russia's invasion of Ukraine. He has also openly criticized Ukrainian President Volodymyr Zelenskyy, calling him an "opponent" and pushing back against sanctions on Russia and certain European Union aid packages to Ukraine.
"As a state, Ukraine is of course very important but in the longer term, strategically thinking, what is at stake is the future security of Europe," Orban said at the forum.
"It is obvious that, without the United States, there is no security architecture for Europe. And this war cannot be stopped ... unless the Russians can make an agreement with the United States. As a European, I am not happy with that. But it is the only way out."
