Russian bombs have killed two people hiding inside a school in Ukraine with up to 60 others feared dead.
Serhiy Gaidai, governor of the Luhansk region, said almost the whole village of Bilohorivka had been sheltering in the building.
Around 30 people were rescued from the rubble following the strike on Saturday afternoon.
However, 60 others are thought to have died under the debris.
Mr Gaidai said: "The fire was extinguished after nearly four hours, then the rubble was cleared, and, unfortunately, the bodies of two people were found.
"Sixty people were likely to have died under the rubble of buildings."
Separately, Mr Gaidai said Russian Grad rockets killed two children in the city of Pryvillya yesterday, with two other youngsters and a woman left injured.
Elsewhere, he added that shelling in the village of Shypilovo had destroyed a house and 11 people remained under the building's debris, according to preliminary information.
It comes after Ukraine and the West have repeatedly accused Russian forces of targeting civilians and war crimes, charges Moscow rejects.
Russia's 10-week-old war on Ukraine has killed thousands, destroyed cities and driven 5 million Ukrainians to flee abroad.
The besieged port city of Mariupol, a strategic target for Russian forces, has been virtually destroyed, with the last 300 civilians trapped in the bombed-out Azovstal steelworks evacuated on Saturday.
Evacuation efforts will now focus on getting the wounded and medics out of the steelworks.
Ukrainian fighters in the plant have vowed not to surrender and Russian forces are seeking to declare a victory in time for Monday's Victory Day celebrations in Moscow.
The event commemorates the Soviet Union's triumph over Nazi Germany in World War Two.
