RIYADH, Saudi Arabia (AP) — Saudi Arabia's state news agency says unidentified gunmen have fired on two German diplomats in their vehicle in an eastern town.

Saudi Press Agency quoted a police chief on Monday as saying that the shooting took place at 6:00 PM in the town of al-Awamiya.

The diplomats' vehicle caught fire but the two survived the attack, the agency said. A German foreign ministry official in Berlin said neither was injured when the car was fired upon and caught fire, but gave no further details, speaking anonymously in line with ministry practice.

The site of the attack is a restive district where Shiites, who make up 10 percent of the kingdom's population, have been staging demonstrations against Saudi Arabia's Sunni rulers. Security forces frequently clash with protesters, arresting and detaining them.
