The death toll from the Ukraine war’s deadliest attack on civilians at one location since last spring, a weekend Russian missile strike on a southeastern apartment building, has reached 45, officials said Tuesday.

Those killed in the Saturday afternoon strike in Dnipro included six children, with 79 people injured, President Volodymyr Zelenskyy wrote on the Telegram messaging app. The toll included two dozen people initially listed as missing at the multistory building, which housed about 1,700, according to Kyrylo Tymoshenko, deputy head of the Ukrainian president’s office.

Emergency crews cleared some 9 metric tons (9.9 tons) of rubble during a non-stop search and rescue operation, the Dnipro City Council said. About 400 people lost their homes, with 72 apartments completely ruined and another 236 damaged beyond repair.
