Saudi Arabia's Interior Ministry security forces have killed two militants before they were able to detonate a car bomb in the southwestern town of Bisha .
Dawn says that Saudi Interior Ministry spokesman Maj Gen Mansour al-Turki said that 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.
