At least 30 people, most of them children, have been wounded after Israeli tanks shelled an area close to an UN-run school in Beit Lahiya in northern Gaza on Thursday.<br /><br />It comes just a day after at least 15 Palestinians were killed in a different UN school, in an Israeli attack condemned by world leaders.<br /><br />Issam Al Attar, who was sheltering in the school, said he despaired of anyone coming to the help of Gaza: “All of them were children sleeping. What are they guilty of? No one cares about them – no feeling. Where is Egypt? Where are the Arab countries?” <br /><br />Now many who were told by the Israeli army they would be safer to leave their homes are considering returning.<br /><br />Samir Al Tumi said there was nowhere safe to go: “We are dying of fear, I want to go and die in my own home rather than die in a UN school because there is no safety here, none whatsoever.”<br /><br />The United Nations childrens’ fund, UNICEF, says at least 245 Palestinian children have been killed during the three-week conflict.
