Ukrainians face new airborne threat that has killed 24 civilians and injured hundreds more since July

Sasha Ustenko has survived three attacks by the Russian drones that stalk the streets of Kherson carrying fragmentation grenades to drop on anything that moves. The first, in late July, targeted a parked police car in central Kherson just as Ustenko walked past, throwing him to the ground. The second, in mid-August, hit a drinking water tanker as he queued for supplies, killing the driver. Ustenko was concussed, and came round to see a man lying in a pool of blood.

The third time, in late September, he heard the drone buzzing above and sprinted for shelter under the branches of a cherry tree. He hoped its leaves would hide him but the grenade tumbled through the canopy and landed barely a metre away.
