The Ukrainian volunteers using drones to defend against the Russians

Russian air strikes and bombardments have killed at least eight people and injured many more in the Donetsk region of eastern Ukraine.

It comes as the Kremlin’s forces seek to take full control of the Donbas.

The city of Slovyansk has found itself on the new frontline, with its remaining residents living under constant shelling. Authorities have called for the tens of thousands of residents left to evacuate the area.

But, Ukrainian volunteers are taking part in a largely unseen battle to defend their territory with drones.
