Dozens of people were reportedly dead after a bomb hit a school in east ukraine, where government forces are battling russian troops and separatists.
Earlier, the governor of luhansk region, Serhiy Haidai, said 90 people had been sheltering in the building in Bilohorivka, and 30 were rescued.
Haidai said a Russian plane had dropped the bomb on Saturday, though his accusation could not be verified independently and there was no immediate response from russia.
Luhansk has seen fierce combat as Russian troops and separatist fighters seek to surround government forces, just over two months since the start of the Russian invasion.
Much of Luhansk, which along with Donetsk forms part of the Donbas region, has been under the control of the separatists for the past eight years.
Bilohorivka is close to the government-held city of Severodonetsk, where heavy fighting was reported in the suburbs on Saturday. One Ukrainian newspaper, Ukrayinska Pravda, says the village became a “hot spot” during fighting last week.
According to the governor’s writing on social media, the blast brought down the building which caught fire and it took firefighters three hours to extinguish the blaze.
He said almost the entire village had been sheltering in the basement of the school.
The final death toll would only be known when the rubble had been cleared, the governor added.
