Russia launched 537 drones and missiles into Ukraine overnight into Sunday morning, according to Ukraine's air force, with a Ukrainian F-16 fighter jet and its pilot also reported lost during efforts to repel the attack.

Russia has launched its biggest aerial attack against Ukraine overnight, part of an escalating bombing campaign that has further dashed hopes for a breakthrough in efforts to end the 3-year-old war.

Russian forces have launched more than 500 aerial weapons at Ukraine overnight, Kyiv said on June 29, describing the attack as the biggest air strike on the country since the war began.
