Throngs of people eagerly waited on Thursday for more than 100 Palestinian prisoners who were released from Israel in exchange for hostages held in Gaza.

An Israeli air strike killed 10 Palestinians in the north of the occupied West Bank on Wednesday night, the Palestinian health ministry says. Video footage reportedly from the town of Tamun showed chaotic scenes, badly damaged buildings and bloodstained streets.

The sudden expansion of Israeli security operations in the West Bank has killed at least 10 people and follows the start of the delicate ceasefire process in Gaza, by which Israeli hostages are released in stages and will also see the gradual withdrawal of Israeli forces.

The action came a day after President Donald Trump said he will lift sanctions on ultranationalist Israeli settlers who attacked Palestinian villages.

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

Israel’s defense minister has announced a series of raids that he says are targeting “terrorism” in the occupied West Bank, as Palestinian officials warned of a “man-made disaster.”

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.
