RIYADH: Saudi Arabia's Interior Ministry says security forces have killed two militants before they were able to detonate a car bomb in the southwestern town of Bisha.

Saudi Interior Ministry spokesman Maj Gen Mansour al-Turki said in a statement carried by the Saudi Press Agency late Friday that security forces tried to stop two cars but the drivers fled and took refuge in nearby mountains before one of the cars exploded.

Al-Turki said the two continued firing at security forces, but were eventually killed with the help of a helicopter gunship.
