Ukraine and Russia attacked targets on each other's territory on Thursday after brief direct talks between the two sides failed to make any progress on steps to end nearly three-and-a-half years of war.

Deaths have been reported on either side of the border, just hours after a third round of ceasefire talks took place in Turkey.

The Washington-based Institute for the Study of War noted that cooperation with China has allowed Russia to bypass Western sanctions on imports of electronics for drone production. Ukraine’s military intelligence estimates that Russia receives up to 65% of components for its Geran drones from China. Beijing rejects the claims.
