Ukrainian President Volodymyr Zelenskyy said more than 300 civilians have been rescued from the besieged steel plant in the southeastern coastal city of Mariupol, in what he called the first phase of an evacuation mission. Zelenskyy said preparations are now under way to get the wounded and doctors out of the plant.
To the north in Luhansk, the regional governor said Russia dropped a bomb on a school where 90 people were taking shelter from the fighting. About 30 people have been saved from the rubble so far, Gov. Serhiy Hadai said.
The World Health Organization has documented 200 attacks on health-care facilities in Ukraine, according to its top official. WHO chief Tedros Adhanom Ghebreyesus said the global health agency stands with the people of Ukraine and called on Russia to end the war.
In Washington, CIA chief William Burns said Russian President Vladimir Putin believes he cannot afford to lose in Ukraine, and will likely double down on the war. In Lithuania, Ukraine's Foreign Minister Dmytro Kuleba called for a special tribunal to prosecute Russia's leadership.
A dress rehearsal for Russia's annual "Victory Day" is underway on Saturday. May 9 will mark the anniversary of the then-Soviet Union's defeat of Nazi Germany in World War II.
Zelenskyy says Russia's actions 'beyond words' after missile destroys museum
Ukrainian President Volodymyr Zelenskyy said that everyday of this war, Russian forces does something that is "beyond words," following a strike against a museum in Ukraine.
"Every day of this war, the Russian army does something that is beyond words. But every next day it does something that makes you feel it in a new way," he said in a regular late-night address on Saturday.
"Targeted missile strikes at museums — this is not even every terrorist can think of," Zelenskyy added.
The museum that was destroyed is dedicated to the 18th century philosopher and poet Hryhoriy Skovoroda.
But this is the kind of army that is fighting Ukraine, and "this is what they want to bring to other European countries," he said.
As of May 7, the Russian army has destroyed or damaged nearly 200 cultural heritage sites, according to Zelenskyy.

UK to provide about $1.6 billion of further military support to Ukraine
Britain said it would provide a further 1.3 billion pounds (US$1.6 billion) in military support and aid to Ukraine, making the pledge ahead of a planned video call on Sunday by Group of Seven leaders with Ukrainian President Volodymyr Zelenskyy.
Prime MinisteBoris Johnson has been one of the strongest supporters of Ukraine's efforts to resist Russian forces since Russian President Vladimir Putin launched the invasion on Feb. 24. Johnson's government has sent anti-tank missiles, air defense systems and other weapons to Ukraine.
The new pledge almost doubles Britain's previous spending commitments on Ukraine and the government said this is the highest rate of spending on a conflict since the wars in Iraq and Afghanistan, although it did not give details of this calculation.
"Putin's brutal attack is not only causing untold devastation in Ukraine — it is also threatening peace and security across Europe," Johnson said in a statement. Last week he became the first Western leader to address Ukraine's parliament since the start of the invasion.
The leaders of the G-7 countries — Britain, Canada, France, Germany, Italy, Japan and the United States — will hold their virtual meeting with Zelenskiy on Sunday, the day before Russia marks its Victory Day holiday, which marks the end of World War II in Europe.
Britain said the extra spending on Ukraine will come from a reserve used by the government for emergencies.

Civilians and soldiers have been barricaded at the massive steel plant since mid-April.
Zelenskyy says preparations are underway for the second phase of the evacuation mission, which includes rescuing the wounded and the doctors.

Ukraine's foreign minister calls for a special tribunal to prosecute Russian leadership

"We need a special Tribunal for the Crime of Aggression against Ukraine to hold Russian leadership to account," Kuleba wrote in a tweet.

Senior Russian lawmaker says U.S. directly involved in Ukraine fighting
Russia's most senior lawmaker on Saturday accused Washington of coordinating military operations in Ukraine, which he said amounted to direct U.S. involvement in military action against Russia.
"Washington is essentially coordinating and developing military operations, thereby directly participating in military actions against our country," Vyacheslav Volodin wrote on his Telegram channel.
Washington and European members of the transatlantic NATO alliance have supplied Kyiv with heavy weapons to help it resist a Russian offensive that has resulted in the occupation of parts of eastern and southern Ukraine but failed to take Kyiv.
However, the United States and its NATO allies have repeatedly said they will not take part in fighting themselves, in order to avoid becoming parties to the conflict.
U.S. officials have said the United States has provided intelligence to Ukraine to help counter the Russian assault, but have denied that this intelligence includes precise targeting data.
Volodin, speaker of the lower house of parliament, the Duma, is a prominent advocate of what Moscow calls its "special operation" in Ukraine to degrade its southern neighbor's military capabilities and root out what it calls fascist elements holding sway over the government and military.
Ukraine and the West say the fascist allegation is baseless, and that Russia has carried out an unprovoked act of aggression. The conflict has killed thousands in Ukraine, and more than five million people have fled the country.
Volodin said foreign advisers had been working in Ukraine since what he called the "coup d'etat", in an apparent reference to President Volodymyr Zelenskiy's democratic election in 2019.
WHO says it stands with people of Ukraine, urges Russia to end the war
The chief of the World Health Organization is appealing to Russia to end its offensive on Ukraine.
"We continue to call on the Russian Federation to stop this war," WHO Director-General Tedros Adhanom Ghebreyesus said in a live media briefing on Saturday.
Tedros said the WHO stands with "all the people of Ukraine" and vowed to support the government in its efforts to treat the injured, maintain health services, and repair and strengthen Ukraine's health systems.
Thus far, the organization has verified 200 attacks on health-care facilities in Ukraine since the war began.
"These attacks must stop. Health care is never a target," Tedros said.
Since Russia invaded Ukraine, the WHO has delivered trauma and emergency supplies, which they say have been put to use in over 15,000 surgeries. The medicines and health-care equipment donated to the cause have served 650,000 people, and the group will donate over 20 ambulances on Sunday, according to the WHO.
The organization has also provided 15 diesel generators to provide electricity to hospitals and health facilities, including in some of the newly accessible regions of the country, including Kyiv.

Russia says its missiles hit airfields in Odesa region, U.S. equipment near Kharkiv
Russia's defense ministry on Saturday said high-precision missiles had destroyed Ukrainian aircraft at airfields in the Artsyz, Odesa and Voznesensk regions, and that its Iskander missiles had hit U.S. and European equipment near Kharkiv.
Ukraine earlier said four missiles had hit the Odesa region on Saturday, without causing casualties.
Other missiles striking Odesa on Saturday had hit a furniture factory in a residential area, while the other two struck an already damaged runway strip, it said.
CIA director: Putin believes he can't afford to lose, may double down to gain an edge in Ukraine war
The Director of the U.S. Central Intelligence Agency warns that Russian President Vladimir Putin doesn't want to lose — and he may dial up the offensive on Ukraine to tip the balance in his favor.
"He's in a frame of mind in which he doesn't believe he can afford to lose," CIA chief William Burns said at a Financial Times event in Washington on Saturday.
"I think he's convinced right now that doubling down still will enable him to make progress," continued Burns.

Ukraine says all women, children and elderly evacuated from Mariupol steel plant
Ukraine's Deputy Prime Minister Iryna Vereshchuk says all women, children and elderly have been evacuated from a Mariupol steel mill long besieged by Russian forces.
"The president's order has been carried out: all women, children and the elderly have been evacuated from Azovstal. This part of the Mariupol humanitarian operation has been completed," she said.
The Russian news agency Tass had reported that 50 civilians were evacuated from the plant on Saturday. A similar number left on Friday.
The civilians had been holding up in the plant with Ukrainian fighters making a final stand to prevent a complete takeover of Mariupol.

Retired Gen. Wesley Clark says war in Ukraine will draw out over the summer
Retired U.S. Army Gen. Wesley Clark said the Biden administration isn't moving fast enough to help Ukraine defeat Russia, threatening to prolong the conflict over the summer.
"The administration is saying the right things, but it's not given the right equipment soon enough to the Ukrainians is my personal view," Clark told CNN. Clark was NATO's Supreme Allied Commander Europe from 1997 to 2000, commanding Operation Allied Force during the Kosovo War.
Clark said there was "no long-war strategy possible for Ukraine." He said the country has a window of opportunity over the summer to eject the Russians, he said.
If Ukraine doesn't get the right support by that time, China will be freed up to do more to assist Russia after Chinese President Xi Jinping is approved for a third term.
"Missile strikes are bit by bit chewing up Ukraine's infrastructure," Clark said. "The United States need to redouble its efforts to get military equipment into Ukraine right now, the kind they can use to eject the Russians now, over the summer."

Russian oligarch Abramovich reaches deal to sell Chelsea soccer club
Chelsea soccer club will be sold to a consortium fronted by Los Angeles Dodgers part-owner Todd Boehly, ending 19 years of ownership and lavish investment by Roman Abramovich until the Russian oligarch was sanctioned and forced to offload the Premier League club over the war in Ukraine.
The sale price of 2.5 billion pounds ($3.1 billion) for the reigning FIFA Club World Cup winners and 2021 European champions is the most lucrative-ever for a sports team worldwide but Abramovich cannot receive the proceeds, which he hopes will go to a foundation for the victims of the war. A further 1.75 billion pounds ($2.2 billion) has been committed to invest in Chelsea's teams and stadiums after two months of rapid negotiations to sell the west London club since Russia invaded Ukraine on Feb. 24.
After several rival bids were rejected, Chelsea said Saturday that buyout terms had been agreed with a consortium that features Boehly along with Dodgers principal owner Mark Walter, Swiss billionaire Hansjorg Wyss and funding from private equity firm Clearlake Capital.
The Premier League must approve them as the new ownership and the government has to sign off under the terms of the license that allows Chelsea to continue operating as a business through May 31 while being one of Abramovich's frozen assets.

Jill Biden meets with U.S. troops, Ukranian refugees in Romania and Slovakia
U.S. first lady Jill Biden traveled to Romania and Slovakia, meeting with U.S. troops and Ukrainian refugees.
Biden made multiple stops with Romanian first lady Carmen Iohannis, who's also an English teacher. Nearly 900,000 refugees have come through the nation so far, a UNICEF official told Biden, who praised the resilience of the women in fleeing Ukraine and appeared to get emotional listening to their accounts.
Anastasia Konovalvoa, a Ukrainian teacher who fled to Romania in March with her three-year-old son, was among those who shared her story with the first lady at a public school in Bucharest.
"Everything I was thinking about was how to save my child from a city that was bombed," she said. "Thank god the Romanian people were here. I think even the Romanian didn't expect that they could be so wonderful because you don't expect that from people."
Biden finished her first stop in Romania by dishing out mac & cheese and potatoes to U.S. service members and then mingling in the mess hall for about an hour. She endeared herself to troops by bringing 5 gallons of Heinz Ketchup on the plane after hearing there was a shortage on base.

West underestimated ‘brutality and ambitions’ of Russia’s Putin, former NATO chief says
Anders Fogh Rasmussen, former NATO Secretary General, told CNBC that Russian President Vladimir Putin is the "big loser" from Moscow's unprovoked onslaught in Ukraine and says the West made mistakes in the run-up to the Kremlin's invasion.
Pro-Russian forces say 50 more people evacuated from besieged Azovstal plant
Pro-Russian forces said 50 more people were evacuated from the besieged Azovstal steelworks in Mariupol, where scores of civilians have been trapped for weeks alongside Ukrainian fighters holed up in the Soviet-era plant.
The territorial defense headquarters of the self-declared Donetsk People's Republic (DPR) said on Telegram that a total of 176 civilians had now been evacuated from the steelworks.
"Today, May 7, 50 people were evacuated from the territory of the Azovstal steel plant in Mariupol," the DPR said.
Reuters could not immediately verify the report.
President Volodymyr Zelenskyy said in a late-night video address on Friday that Ukraine was working on a diplomatic effort to save defenders barricaded inside the steelworks. It was unclear how many Ukrainian fighters remained there.
"Influential intermediaries are involved, influential states," he said, but provided no further details.
The defenders have vowed not to surrender. Ukrainian officials fear Russian forces want to wipe them out by Monday, in time for Moscow's commemorations of the Soviet Union's victory over Nazi Germany in World War II.
Images show Moscow's dress rehearsal of 'Victory Day' parade
The Kremlin's preparations are underway for the country's annual "Victory Day" commemorations on May 9.
The 77th anniversary of the then-Soviet Union's defeat of Nazi Germany in World War II comes more than two months after the Kremlin launched its unprovoked onslaught on Ukraine.

Ukraine's counteroffensive around Kharkiv enters decisive phase, think tank says
Ukrainian forces have secured further gains north and east of the city of Kharkiv in the last 24 hours, according to the U.S.-based Institute for the Study of War.
The respected think tank says the counteroffensive could soon see Ukrainian forces push Russian forces out of the artillery range of Kharkiv.
"This Ukrainian operation is developing into a successful, broader counteroffensive—as opposed to the more localized counterattacks that Ukrainian forces have conducted throughout the war to secure key terrain and disrupt Russian offensive operations," the Institute for the Study of War said in an update.

Ukraine conflict 'taking a heavy toll' on Russia's most capable units, UK’s Defence Ministry says
The Ukraine conflict is heavily affecting some of Russia's most capable units, said the U.K.'s Defence Ministry in its daily intelligence update.
"The conflict in Ukraine is taking a heavy toll on some of Russia's most capable units and most advanced capabilities," the ministry said in its update, posted on Twitter.
"It will take considerable time and expense for Russia to reconstitute its armed forces following this conflict," it added.
At least one T-90M, Russia's most advanced tank, has been destroyed in fighting, the update said.
"It will be particularly challenging to replace modernised and advanced equipment due to sanctions restricting Russia's access to critical microelectronic components," the ministry added.

Russia must pull back forces to pre-invasion position before any peace deal can happen, Zelenskyy says
Ukrainian President Volodymyr Zelenskyy told London think-tank Chatham House that any peace deal with Moscow would be dependent on Russian forces pulling back to their positions before the war, the BBC reported.
Zelenskyy said that was the minimum that Ukraine could accept, according to the report. He added that there could be no question of Russia holding on to territory it has taken since the invasion started.
"I was elected by the people of Ukraine as president of Ukraine, not as president of a mini Ukraine of some kind. This is a very important point," he said, according to the BBC report.
