Russia-Ukraine live updates: Nearly 10 million have fled since invasion but defiant defense stalls Russian advance

Photographer Kasia Strek, on assignment for The Washington Post, filed this dispatch from Lviv, in western Ukraine, where people are trying to flee the fighting.

Strek visited a train station where the exodus is ongoing. There, she captured these poignant scenes.

Ukrainian President Volodymyr Zelensky said around 130 people survived the Russian attack on a theater in Mariupol this week, though some of them had sustained serious injuries.

In a video address released early Saturday on his Telegram channel, he said he had no information on the number of dead.

Zelensky warned Russians that attacks on civilian targets would result in additional sanctions against Moscow and turn more countries into supporters of Ukraine. “Therefore negotiations on peace, on security for us, for Ukraine — meaningful, fair and without delay — are the only chance for Russia to reduce the damage from its own mistakes,” he said.

The Ukrainian leader said thousands of people had been evacuated from besieged cities, including Mariupol, via humanitarian corridors. But while hundreds of tons of much-needed supplies had been delivered, he said, Russian forces were impeding shipments to those cities “in most areas,” holding the supplies hostage until local Ukrainians cooperated with them.

“This is a war crime. They will be held accountable for this. One-hundred percent,” Zelensky said.

Russian attacks continued on the cities of Kyiv, Kharkiv and Mariupol. A preschool and an apartment building were damaged in Kyiv, and The Washington Post also recently witnessed evidence that cluster bombs were used in Kharkiv.

RIGA, Latvia — Ukrainian officials said Friday that Russian strikes hit a repair facility near an airport in Lviv and a residential neighborhood with a preschool in Kyiv, spawning fresh terror and signaling that the Kremlin’s offensive is becoming more aggressive and indiscriminate as it pushes west through the country.

The missile and rocket attacks came as Ukrainians continued to sort through the catastrophic damage that has come with the three-week-old war, especially in the besieged southern port city of Mariupol, where a theater full of people seeking refuge was bombed earlier this week. A Ukrainian official said 130 people have been rescued alive from the theater that was hit — although the fate of an estimated 1,300 others who had been sheltering there remained unknown Friday. The figures could not be independently verified.
