Russia said on Sunday that Ukraine killed at least 28 people, including nine women and a child, when its armed forces struck a bakery and restaurant in Russian-controlled eastern Ukraine with western-supplied rockets.

Russian-backed officials said that Ukraine struck the bakery in the city of Lysychansk on Saturday with US-supplied High Mobility Artillery Rocket System. Emergency workers worked through the night searching for survivors in the rubble of what remained of the shattered Adriatic Restaurant on Moskovska Street, where Russian officials said a bakery had been set up for civilians.

“The armed forces of Ukraine opened fire on a bakery in Lysychansk,” said Leonid Pasechnik, the Russian-installed head of the Luhansk region which is now controlled by Russian forces.

Pasechnik said the bakery was crowded with civilians when it was struck. Russia’s emergency ministry said 10 people had been pulled from the rubble alive. But the ministry said four more people were in an “extremely grave condition” and that it was still searching for people.
