A dozen other people were injured, some seriously, in the attack in the city of Sumy, which has come under increased bombardment since Ukraine’s offensive into Russia’s nearby Kursk region.

Ukraine said it destroyed a large weapons stockpile in Russia overnight using long-range drones to stage the attack as Kyiv awaits US permission to use western-made missiles in such operations.
