KYIV, Ukraine — Rescuers began to pull survivors Thursday from the rubble of a nighttime airstrike on a theater where more than 1,000 people had sheltered in the besieged port city of Mariupol, as Russia’s war on Ukraine entered its fourth week with no sign of a respite and a new onslaught of attacks on civilian sites.
On Thursday, the International Rescue Committee said at least 20 people were killed and 25 injured in an attack on a school in the city of Merefa.
And in eastern Ukraine, a public pool facility where civilians had been sheltering was also hit, officials said, although it was unclear whether there had been casualties.
