GENEVA: The head of a UN investigation said on Monday that an Israeli air strike on a prison last year was a war crime, and warned of risks of further repression following the current US-Israeli bombings. More than 70 people were killed when Israel struck Tehran’s Evin prison last June during an air war with Iran, Iranian authorities have said. The jail, known for holding political prisoners, has also been damaged in the latest US-Israeli air strikes, raising fears for the detainees, who include a British couple.
