A Russian drone strike injured at least four people and caused damage to a seven-story residential building in the Ukrainian city of Kharkiv on Wednesday, November 13, according to Ukrainian officials.

Russia attacked the southern city of Mykolaiv with drones on Nov. 11, killing five people and injuring one woman, local authorities reported. Five people were killed and one 45-year-old woman was hospitalized following the attack,

Russia overnight launched a “record” 145 drones at Ukrainian territory, according to Ukraine’s air force, 62 of which were shot down. A further 67 were “lost,” the air force said, a likely reference to electronic jamming that caused the drones to veer off course.
