Israel and Gaza have both suffered their bloodiest day since the beginning of the current offensive.
Israel says that 13 of its soldiers died since Saturday night, the biggest one-day loss for its army in years.
At least 87 Gazans were reported killed on Sunday - 60 of them in the district of Shejaiya alone.
