A Russian drone attack on a residential block killed nine people including three elderly couples in the eastern Ukrainian city of Sumy, officials said on Thursday. Moscow has pummelled Ukrainian cities with dozens of drones or missiles almost daily since it invaded in early 2022.

The drone blew out a wall and surrounding windows in the building in Sumy, a major city, just after 1 a.m., the Sumy regional administration said.

Kyiv says it struck a Russian oil refinery and a microchip factory in attack which Moscow says contained 120 drones
