RAMALLAH (Reuters) - Six Palestinians were killed and 18 others injured by Israeli forces during a military raid in the occupied West Bank city of Qabatiya, the governor of Jenin told Reuters on Thursday.

The governor, Kamal Abu al-Rub, said four of the injured are in critical condition, and that Israeli forces withdrew from Qabatiya after destroying infrastructure in the area.

There was no immediate comment from the Israeli military.

Violence has surged in the West Bank since the start of the war in Gaza, with almost daily sweeps by Israeli forces that have involved thousands of arrests and regular gunbattles between security forces and Palestinian fighters.
