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.

In the days since a fragile ceasefire took hold in the Gaza Strip, Israel has launched a major military operation in the occupied West Bank and suspected Jewish settlers have rampaged through two Palestinian towns.
