A vehicle owned by the German embassy was hit by gunfire from unknown assailants in Awwamiyya town, a police spokesman said. "The vehicle was burned, but the two German diplomats onboard survived the incident with the help of a Saudi citizen," Xinhua quoted him as saying.
Saudi security authorities have launched an investigation into the incident.
One week ago, Qatif governorate, with a high Shiite population, witnessed heavy shooting by unknown assailants who targeted a police vehicle, which led to the death of a policeman.
The Saudi interior minister released two years ago a list of 23 wanted individuals on rioting and random shooting charges in Qatif. Names on the list have dropped to eight after most of the suspects were arrested.
