Russian rockets hit the eastern Ukraine town of Chasiv Yar, destroying a five-story apartment building and killing at least 15 people, officials say.
Pavlo Kyrylenko, governor of the Donetsk region, says about three dozen people could be trapped in the rubble. Rescuers have made contact with two people who are under the wreckage, he writes on the Telegram messaging app.
The Ukrainian emergency services initially gave a death toll of six, but later said it has risen to 10, and now 15. They did not say how many people may still be in the rubble.
