Gaza, July 20 (ANI): At least 40 Palestinians were killed on Sunday by Israeli shelling in a Gaza neighbourhood, where bodies were strewn in the street and thousands fled toward a hospital packed with wounded, health officials said. The mass casualties in the Shejaia district in northeast Gaza were the heaviest since Israel launched its offensive on the Palestinian territory on July 8 after cross-border rocket strikes by militants intensified. There were no signs of a diplomatic breakthrough towards a ceasefire, and militants kept up their rocket fire on Israel.
