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 Russian overnight air attack wounded eight residents of an apartment building in Kyiv, including a three-year-old child, authorities said on Monday, while the Ukrainian air force said a town hosting a key air base had been attacked.
