Desperate Ukrainians have started attacking each other for food and looting pharmacies in the besieged port of Mariupol as the situation there becomes “increasingly dire,” a Red Cross official warned Thursday.

Sasha Volkov, who is deputy head of the Red Cross delegation in Mariupol and is among those seeking shelter, painted a grim picture of what was unfolding amid the endless shelling attacks from Russian forces.

“All the shops and pharmacies were looted four to five days ago,” Volkov said in a three-minute voice message sent to his colleagues via a satellite phone.
