At least 12 people were killed when a Russian drone struck a bus carrying miners in Ukraine’s central-eastern Dnipropetrovsk region, Ukrainian authorities said on Sunday. The bus was traveling near the city of Ternivka, about 65 kilometers from the front line. Energy company DTEK confirmed that all victims were returning from work at one of its mines. Photos released by Ukraine’s State Emergency Service showed shattered windows and a damaged windshield.

Regional military administrator Oleksandr Hancha reported on Telegram that the drone hit a company shuttle bus in the Pavlohrad district, injuring at least seven others. The AFP news agency said it could not independently verify the circumstances of the attack. Hancha also reported that a separate overnight drone strike in the city of Dnipro killed a man and a woman.

The attacks occurred as the deadline expired for a unilateral reduction in Russian strikes announced by U.S. President Donald Trump. Trump had claimed Russian President Vladimir Putin agreed to halt winter assaults on Kyiv and other cities, though the terms remained unclear and the Kremlin did not confirm any weather-related ceasefire.
