The Israeli military has told more than one million Gaza residents to leave their homes in advance of further airstrikes and an expected ground operation in retaliation for last Saturday's Hamas terror attacks in Israel. More than 3,100 have died in seven days and Prime Minister Netanyahu says this Israeli campaign was "only the beginning." Amna Nawaz and Leila Molana-Allen report from Tel Aviv.
