More Israeli soldiers' lives have been saved in this war compared to previous Gaza wars, due to medical advances, new technology and lessons learned on the operating table.
The Israeli military says its expanded operation in Gaza City "to destroy Hamas' military infrastructure" has begun, forcibly displacing hundreds of thousands of people.
The White House expressed disapproval with the attack, saying a unilateral strike in a country that's a U.S. ally "does not advance Israel or America's goals," and tried to tip off Qatar in advance.
