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

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.

Russia and Ukraine launched drone strikes against each other early on July 24, officials from both sides said, as fierce fighting continued to rage along the battlefield.
