Ukraine has issued increasingly urgent calls for more Western heavy weapons to help defend Sievierodonetsk, which Kyiv says could hold the key to the battle for the eastern Donbas region and the course of the war, now in its fourth month.
On Monday Gaidai had said on social media that some 70 per cent of the city was under enemy control, and the destruction of the last bridge across the river to the twin city of Lysychansk meant any civilians still in Sievierodonetsk were trapped, and it was impossible to deliver humanitarian supplies.
