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

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.

A separate Russian drone and missile barrage wounded seven people including a child in the central Ukrainian region of Cherkasy, emergency services said. And in the southern port city of Odesa, a Russian drone attack wounded four people and badly damaged a market.
