The drone attack destroyed a Russian military arsenal in Tver, triggering a blast powerful enough to be detected by earthquake monitors and NASA satellites.

The Ukrainian air force said Sunday it shot down 10 of the 14 drones and one of the three missiles Russia launched overnight, while the rest hit the suburbs of Odesa. Oleh Kiper, Odesa's regional governor, said the two who died Saturday night were a married couple, and that another person was wounded in the attack.
