“Another Russian war crime. Today, the occupier attacked vehicles of the International Committee of the Red Cross humanitarian mission in the Donetsk region,” President Volodymyr Zelensky said on X.

The village of Viroliubivka came under shelling, regional governor Vadym Filashkin said on the Telegram messenger app, reporting casualties.

The prosecutor-general’s office said on Telegram that ICRC employees had brought fuel briquettes to residents for heating before winter.

They were unloading the aid when the attack happened, it said.

Two employees were hospitalised, and one was in severe condition, prosecutors added.

The Donetsk region, which Russian troops partially occupy, regularly comes under Russian shelling and air strikes.

Moscow denies targeting civilians or civilian infrastructure in its invasion of Ukraine, although thousands of people have been killed in its attacks.
