The Iranian Red Crescent said Monday that three of its rescuers were killed by an Israeli air strike in northwest Tehran while aiding the wounded. “This incident is not only a crime against international humanitarian law but also a blatant attack on humanity and morality,” the organisation said, adding that the workers were helping the injured in Tehran’s Shahid Bagheri district. This is at least the second time the Red Crescent has been targeted by Israeli strikes. Last Saturday, the organisation said an Israeli attack hit one of its ambulances in the country’s northwest, killing two people.
