A Russian oil refinery in the southern Volgograd region caught fire after being hit by debris from a Ukrainian drone attack. Regional Governor Andrei Bocharov confirmed the overnight attack, saying on Friday that the blaze was “promptly extinguished” and one injured worker was hospitalised.

Officials say a Russian drone has blasted a hole in an apartment building in northeastern Ukraine during a nighttime attack that killed at least six people and wounded nine others.

A Russian drone struck a multi-storey apartment building in the northeastern Ukrainian city of Sumy early on Thursday, killing nine people and injuring 13, including a child, President Volodymyr Zelenskiy said.
