Twelve people were reported killed in Ukraine, with its air force saying 22 locations were hit by Russian air strikes.

The first direct peace talks between Russia and Ukraine in more than three years lasted well under two hours, with no apparent sign of progress so far in narrowing the gap between the sides, and a Ukrainian source called Moscow's demands "non-starters".

The exchange came hours after Kyiv came under a large-scale Russian drone and missile attack that left at least 15 people injured.
