Blocked from all sides with no means of escape, Gaza’s 1.5 million people are trapped between Hamas fighters and Israeli troops. More than 4,000 people have been injured, mostly civilians, and aid agencies say the fighting often prevents medics from reaching those in need. Gaza’s overstretched emergency services are struggling to cope:“(We get) many casualties every day, most of them are civilians,” said ICRC surgeon Dr Mauro Della Torre. “We take care of very few combatants. So, every day we have to face the reality that most of these patients are civilians.” The fighting has raised concern about a looming humanitarian disaster in Gaza. The three-hour lull in fighting that Israel sometimes allows to move humanitarian aid into Gaza is not enough, according to aid workers who say hundreds of thousands are still without food, electricity and clean water.
