Palestinian police said they arrested 11 people after uncovering a weapons cache and a bomb lab in the city of Hebron.

Hebron is the West Bank's largest city and considered a Hamas stronghold. Security forces loyal to moderate Palestinian President Mahmoud Abbas have been cracking down on the Islamic militants in the past year. Hamas seized Gaza by force in June 2007 and Abbas is trying to prevent a repeat in the West Bank.

A weapons storehouse and an explosives lab have been discovered in Hebron in recent days and that 11 Hamas activists have been arrested, Police Col. Ramadan Awad said.
