The United Nations will start pulling its workers out of Gaza as the conflict with Israel claims a growing number of aid workers, medical personnel and journalists, including two reporters killed in strikes on Monday. UN Secretary-General Antonio Guterres said the organisation had made the “difficult” decision to withdraw a third of its international workers, after repeated Israeli strikes on its facilities in Gaza. A Red Cross building was also hit in Gaza on Monday, in what Israel said was a mistake. The UN has lost more workers during the 18-month war than in any other conflict in its history, Guterres says. At least 280 have been killed, among them a Bulgarian UN worker killed in a strike on a UN compound last week, which the UN says came from an Israeli tank, a claim Israel denies. A 23-year-old Palestinian journalist, Hossam Shabat, was killed in a strike on his car in northern Gaza on Monday, with footage verified by The New York Times showing his body, and those of two other men, lying beside a car bearing the Al Jazeera emblem, and the letters “TV” on the windshield. The car was peppered with what appeared to be bullet or shrapnel holes, the paper reported.
