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.

The Israeli military launched a major offensive in the West Bank on January 21 aimed at rooting out Palestinian armed groups from the Jenin area, which has long been a hotbed of militancy.

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.
