By Friday, at least 110,000 Palestinians had been forced to flee Rafah, which is now under bombardment. Many of them have already been displaced two or three times. But all of them know nowhere is safe in Gaza now. There’s no refuge, no place free of bombs and tank shellings and sniper fire, no tent camp or temporary shelter with a reliable source of water or working toilets or beds or food, no mosque to pray in as death hovers all around.
