As Israel withdraws some of its troops from Gaza during a cease-fire there, it has turned attention to another Palestinian territory — in particular a city with a history of militant activity.

Prime Minister Benjamin Netanyahu said the assault on Jenin would be “extensive and significant,” as the military erected new checkpoints across the West Bank.

The city of Jenin, a Palestinian militant stronghold in the Israeli-occupied West Bank, has become a new front for Israel days after it reached a ceasefire deal with Hamas that suspended a 15-month-old war in Gaza.
