The death toll from a weekend Russian missile strike on an apartment building in southeastern Ukraine climbed to 41 on Tuesday after the body of a child was pulled from the rubble, officials said, in what was the deadliest attack of the war on civilians at one location since the spring.

Another 25 residents of the building city of Dnipro were still missing, according to Valentyn Reznichenko, the governor of the Dnipropetrovsk region, whose capital is Dnipro.

Emergency crews have cleared about 90% of the rubble during a 63-hour search since the Saturday afternoon strike, he said.

There are 79 wounded people, he said, with 28 of them hospitalized and 10 in serious condition. About 1,700 people lived in the multistory building. Some people were trapped on upper floors, with some signaling for help with lights on their cellphones.

The latest deadly Russian strike on a civilian target in the almost 11-month war triggered outrage. It also prompted the surprise resignation on Tuesday of a Ukrainian presidential adviser who said the Russian missile was shot down by the Ukrainian air defense system and exploded when it fell — a version that would take some of the blame off the Kremlin’s forces.
