Israel stationed tanks outside Jenin refugee camp on Monday (February 24), one day after tanks were sent into the Israeli-occupied West Bank for the first time in more than 20 years.

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.

Palestinian militants said on Monday that an unusual deployment of Israeli tanks in the occupied West Bank, part of a major offensive that has displaced tens of thousands, may be a step toward annexation.
