The Israeli army has been accused of deliberately targeting Palestinian refugees, after 30 people died in one house in Zeitoun. The United Nations said 110 people were told by Israel to shelter there last weekend, but the building was bombed by Israeli forces 24 hours later. Rescuers said the victims had no chance.“Several bombs hit the house,” said one man. “Some people managed to escape, but others were trapped. Most of them were children, too young to flee. We managed to collect the bodies. Some of them were completely blown apart.” Only now have the remains been moved to the morgue. The UN said survivors were forced to walk to the nearest hospital – three children, one just five months old, died on the way. The Israeli army denied any knowledge of the incident, but said it would launch another inquiry. Some Palestinians are sheltering in UN-run schools, even after two schools were hit by Israeli shells. The Red Cross also blamed Israel for preventing rescuers reaching victims of the bombing. It said it knows of places in Gaza where wounded Palestinians are trapped beside the bodies of the dead.
