The White House has not commented on a report finding famine in Gaza. Analysts say that absent U.S. pressure, Israel is unlikely to change course.

"An entire population is being pushed into starvation, destitution, and death,” said Belgium's Deputy Prime Minister.

A UN-backed report warns that Gaza is facing a man-made famine affecting hundreds of thousands, while Israel prepares for a major offensive.

An announcement of famine — as has now happened regarding Gaza — is a complicated decision. Here's what must be considered before such a declaration is made.

The U.N.-backed Integrated Food Security Phase Classification said that famine is occurring in Gaza City -- a first in the Middle East -- home to hundreds of thousands of Palestinians, and that it could spread south by the end of next month.
