The Israeli military blew up several buildings in the occupied West Bank on Sunday in a series of simultaneous explosions that the Palestinian state news agency said had leveled around 20 buildings in the Jenin refugee camp.

A series of explosions tore through the city of Jenin, in the occupied West Bank, sending plumes of smoke into the sky.

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.

Eyewitnesses reported a “large” deployment of Israeli forces around Tubas and Tamun, the scene of recent violence

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.

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.
