Saudi police are investigating the shooting death of an American man in the capital city, Riyadh.
Witnesses say the man was shot on Saturday in a parking garage in front of his home. It is unclear from their accounts whether he was in his car at the time and whether the attackers approached him on foot or killed him in a drive-by shooting.
It is the third shooting of a Westerner in the Saudi capital this week.
There are also reports that Saudi police have found a car rigged with explosives in northern Riyadh.
Arabic television channel Al-Arabiya says the car was found outside a university for Islamic studies (Imam Mohammed Bin Saud Islamic University). No further details were immediately available.
