 At least one person was killed and 16 others were wounded in a Russian drone attack on the northern Ukrainian city of Sumi on July 3, local authorities said. An official building and two residential buildings were damaged in an attack carried out with four drones, the Sumi Regional Administration said on Telegram, the messaging app. Video obtained by Reuters showed an object flying low over Sumi city center and going down, after which an explosion could be heard, closely followed by a second explosion. Kiev's military had earlier on Monday reported shooting down 13 of 17 Iranian-made Shahid drones launched by Moscow overnight in a separate attack on several parts of the country. Russia, which launched its full-scale invasion of Ukraine in February 2022, has stepped up airstrikes against Ukraine in recent weeks, and Ukraine has launched a counter-offensive to try to retake occupied territory.
