Israel is carrying out a military operation in the occupied West Bank and more than 40,000 Palestinians have been forced out of their homes, according to Israeli officials and the United Nations. CBS News' Debora Patta reports.

Israel launched a major military incursion in the northern West Bank in August, which it called “Operation Summer Camps.” It sent armored vehicles into the cities of Jenin and Tulkarem, severing water and electricity and leading Palestinians to ration food, residents told CNN.
