Ukraine soldiers describe ‘almost daily’ illegal gas attacks as invaders seek to dislodge them from embedded positions

Russia has been accused of systematically using illegal chemical gas attacks against Ukrainian soldiers.

Ukrainian troops told the Daily Telegraph that they have been subjected to regular attacks from small drones dropping teargas and other chemicals.

The use of such substances, which is known as CS, is banned during wartime under the Chemical Weapons Convention.

Moscow was accused of using chemical weapons in a drone assault on the port of Mariupol in the early stages of its invasion in February 2022.
