Khan Younis: A Gaza city on its knees, now with a million mouths to feed

A tide of humanity has washed into Khan Younis.

Hundreds of thousands fled here from the north on whatever could carry them - cars if there was fuel, horse and cart if one could be found, their own feet if there was no other option.

And what they found was a city on its knees, ill-prepared for its population to literally double overnight.

Every room, every alley, every street is packed with men, women and the young. And there is nowhere else to go.

Hamas say 400,000 of the 1.1 million people who call northern Gaza home headed south down the Salah al-Din Road in the last 48 hours, following Israel's order to leave.

I was among them, along with my wife and three children, and two days' worth of food.
