Former US president Obama criticizes Israel over cutting off food and water to Gaza

In rare comments on an active foreign policy crisis, Obama said any Israeli military strategy that ignores the human costs of the war "could ultimately backfire."

"The Israeli government's decision to cut off food, water and electricity to a captive civilian population (in Gaza) threatens not only to worsen a growing humanitarian crisis; it could further harden Palestinian attitudes for generations, erode global support for Israel, play into the hands of Israel's enemies, and undermine long-term efforts to achieve peace and stability in the region," Obama said.
