A gunman opened fire on guards at the US Consulate in Jiddah on Friday, and the guards shot back, wounding the man, a security spokesman said.
The gunman was arrested and security officials were questioning him, Interior Ministry spokesman Mansour al-Turki. It was not immediately known if the gunman was linked to Islamic militant groups who have carried out attacks in the kingdom over the past three years.
There were no other reports of injuries in the shooting.
The man fired on the consulate guards as he drove by in his car, al-Turki said. "The guards returned fire wounding the man," he said.
