An Israeli scheme to move hundreds of thousands of already uprooted Palestinians to a so-called "humanitarian city" in Gaza has led politicians to spar with the defence establishment, but officials say a practical plan has yet to be crafted.

A planned “humanitarian city” inside Gaza intended to hold hundreds of thousands of Palestinians would be a “concentration camp,” former Israeli Prime Minister Ehud Olmert has warned.

Plans first suggested by defence minister propose keeping 600,000 Palestinians in area and not allowing them to leave.

Bodies were brought to a hospital in Gaza City after the latest Israeli strikes on the area killed 22 people, including 11 children and three women, according to health officials.

An Israeli military official said, "we are reinforcing forces in the Golan Heights and along the border, ready for a multitude of scenarios."
