What Israel is calling "Operation Iron Wall" against Palestinian armed groups has triggered an exodus of around 40,000 people from four camps in the north of the occupied West Bank: Tulkarm, Nur Shams, Jenin and Far'a.

The Israel Defense Force confirmed Sunday that it has deployed tanks to the West Bank as it expands counter-terrorism operations in Jenin.

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.

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.

Israeli tanks were deployed in the West Bank this morning for the first time in more than 20 years, as the Israel Defense Forces (IDF) said it was expanding an ongoing anti-terror operation in the north of the territory.
