An Israeli military airstrike killed more than 70 members of an extended family, including a veteran UN aid worker, as the UN secretary general warned that the scale of death and destruction inside Gaza is blocking delivery of desperately needed aid.
Issam al-Mughrabi, 56, was killed with his wife, five children and dozens of other relatives in a bombing near Gaza City, said the head of the UN development programme (UNDP) in a statement that also called for an urgent ceasefire.
