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 Israeli military killed at least seven Palestinians in the occupied West Bank on Tuesday as the prime minister announced the start of a “large-scale military operation” in the restive city of Jenin.
