More dead terrorist scum.

Security forces in the Saudi Arabian capital Riyadh have killed five suspected militants believed to be linked to an attack on an oil plant.

Security sources say a siege took place at a villa in a Riyadh suburb in which shots were fired and grenades thrown.

The Saudi interior ministry said one other suspect had been arrested elsewhere in the capital.

An Islamic website has claimed al-Qaeda was behind the foiled attack on Friday on an oil processing plant in Abqaiq.

Interior ministry spokesman Maj Gen Mansour al-Turki said two simultaneous raids had taken place on Monday morning, leading to the deaths of five suspects in a shoot-out and the arrest of a sixth.

That sure brightens up my day.
