CNN’s Don Lemon is at the site of an industrial facility used for fuel storage in Lviv, Ukraine, where a blazing fire and thick black smoke are rising.
“According to the mayor, he believes it is a Russian military strike on this facility,” Lemon reported.
Lviv Mayor Andriy Sadovyi said that “habitable infrastructure was not injured,” in a tweet confirming the burning of the facility. Firefighters and first responders are on the scene. Residents of a nearby neighborhood are also outside waiting for more information.
Sadoyvi advised residents to continue staying in shelters until the air alarm stops.

From CNN staff and Olga Voitovych
The mayor of the northern Ukrainian city of Slavutych was released by Russian forces Saturday after being detained, the Ukrainian political party Sluha Narodu said in a statement.
“The abducted mayor of Slavutych is already at large,” a statement said. “Rallies [against the Russians] continue in the city.”
Russian troops on Saturday entered the city, which was built for workers at the Chernobyl nuclear power plant, sparking protests by residents.
In a video posted on Facebook, Mayor Yuri Fomichev was shown addressing residents on Saturday and telling them that they would have to “communicate with the occupiers” after Russian troops entered the town. Fomichev told residents the Russians would search for weapons but would leave the center of the city.
“They will check whether there is a weapon or whether someone is hiding with it. They will go to the police, they will go to the military recruitment office. It’s clear. They will do a spin [through town] here until noon. After lunch, they have to leave the city. There will be one checkpoint, and they will not be in the city. We are governing the city ourselves,” he said.
Fomichev added: “If someone needs to leave the city, we will agree on the procedure. We realize that now we must communicate with the occupiers. There is no other option. We do not have … machine guns, grenade launchers, missiles, tanks. … We do have hands, brains and hearts. This is the main thing we have. And love for Ukraine, for Slavutych!”

Ukrainian officials said Russian forces struck near the western Ukrainian city of Lviv, without providing extensive details.
Maksym Kozytsky, head of Lviv regional military administration, said: “There were three powerful explosions near Lviv from the Velyki Kryvchytsi side, now there is an air alarm, so keep calm and stay in shelter.”
“The Russian army struck at Lviv,” Lviv Mayor Andriy Sadovyi said on Twitter. “We are waiting for information from the Military Administration. Stay in the shelters.”
The blasts were audible on the street in center of Lviv.
Sadovyi warned in a followup tweet that there could be more strikes after explosions were heard in the city.
“It is possible that shelling will be repeated. Stay in the shelter!” the mayor tweeted.
At least two missiles struck Lviv Saturday, and there are reports of at least five people injured, according to Kozytsky.
He added there are still threats for more missile strikes, according to a post on his official Facebook account.
“Information about what was involved in a residential building or other infrastructure objects was not confirmed,” Kozytsky said.
London’s mayor “embarrassed” by UK’s response in helping Ukrainian refugees
From CNN’s Peirre Meilhan

London Mayor Sadiq Khan said the British government has “got to make it far easier” for Ukrainian refugees to come to the United Kingdom.
Khan, in an interview with talk radio station Leading Britain’s Conversation, added that he is “embarrassed” by the UK’s response so far compared to other countries in Europe on the issue of refugees.
“There’s a disconnect between the actions of Brits and the actions of Londoners and the actions of our government and those in Parliament, as you have seen people across the country, including in London, opening their homes to Ukrainian refugees. You have seen the massive generosity in relation to donations,” Khan said, as he contrasted this with how “it is really hard though for Ukrainians to come here.”
Earlier in the day, Khan attended the London Stands With Ukraine march in solidarity with Ukrainians and to protest Russia’s invasion of the country.
More than 3.7 million refugees have fled Ukraine since the beginning of the invasion, the United Nations’ Refugee Agency said Friday.

Biden says Putin is “a butcher” after speaking with refugees
From CNN’s Kyle Blaine

US President Joe Biden called Russian President Vladimir Putin a “butcher” after visiting with Ukrainian refugees in Warsaw, Poland, on Saturday.
Asked by reporters traveling with the President what seeing the refugees made him think as he deals with Putin every day, Biden responded, “he’s a butcher.”
During the brief question-and-answer session at Stadion Narodowy, Biden recounted how he had been to places like this in his life, but said he is always surprised by “the depth and strength of the human spirit.”
“It’s incredible, it’s incredible. See all those little children. Just want to hug, just want to say thanks. I mean, it’s, just makes you so damn proud,” he said.
He added: “Each one of those children said something to the effect, ‘Say a prayer for my dad or my grandfather or my brother who’s back there fighting.’ And I remember what it’s like when you have someone in a war zone. Every morning you get up and you wonder. You just wonder. And you pray you don’t get that phone call.”
Kremlin’s reaction: The Kremlin responded to Biden’s comments in Warsaw, saying his remarks “narrow the window of opportunity” to repair US-Russia relations, according to Russian state news agency TASS.
Spokesperson Dmitry Peskov told TASS that “the leader of a nation must keep a sober head.”
“Of course, every time these personal insults narrow the window of opportunity for our bilateral relations under the current [US] administration. One has to be aware of this,” Peskov said, according to TASS.

Biden calls Ukrainian refugees “brave” while meeting them in Poland
From CNN’s Allie Malloy

US President Joe Biden spent time with refugees in Warsaw Saturday, meeting with families who were forced to leave Ukraine.
One woman Biden spoke with told him she was there with her daughter, but her husband and son are back in Ukraine fighting.
“It’s frightening,” Biden told her.
The woman, via a translator, spoke about the horror her family has endured and said that “Ukrainian mothers are ready to strangle [Russian President Vladimir Putin] with our bare hands.”
Biden then picked up a little girl in a pink jacket and took out what appeared to be his own phone and took a selfie with her and her family there. The President said he doesn’t speak Ukrainian, but he wanted someone to tell the girl that “I want to take her home.”
“Thank you for everything,” they repeatedly told Biden.
“You’re all brave, brave, brave,” Biden told the family.
