At least 50 Palestinians were killed on Sunday by Israeli shelling in the Gaza neighbourhood, where bodies were strewn in the street and thousands fled for shelter to a hospital packed with wounded, witnesses and health officials said. Militants kept up their rocket fire on Israel, with no sign of a diplomatic breakthrough toward a ceasefire in sight.
