Guardian Video: Gaza: UN-run school devastated after Israeli attack

"Survivors show the ruins of a UN-run school shelter in Beit Lahiya, northern Gaza, on Thursday. At least 30 people, mostly women and children, were injured in what is believed to be an Israeli shelling. The attack follows that on another UN shelter on Wednesday in which at least 15 people were killed. In another part of Gaza, a family escaped death after evacuating their home moments before it was destroyed in an air strike."
