At least 25 people have been killed across Ukraine in overnight and early morning Russian air strikes that hit a prison and a hospital, local officials say. They say the deadliest attack was on the Bilenke penitentiary in the southern Zaporizhzhia region, where 16 inmates were killed and more than 50 injured.

An attack on a prison in the south-eastern Zaporizhzhia region of Ukraine on Monday reportedly left 16 prisoners dead and almost 100 injured, violating international law, the UN Human Rights Monitoring Mission in Ukraine (HRMMU) has said.
