As the Gaza war rages, Egypt fears for its stability

From 10m-high walls and watchtowers Egypt’s soldiers look out on the war unfolding in Gaza. Over half of the coastal enclave’s population of over 2m are on the move, as Israeli tanks advance into it from the north and east and its warplanes and artillery continue their bombardment. Many Palestinians are heading towards the border with Egypt in search of food, electricity, water and safety.
