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.

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.
