State-linked Saudi news sites are reporting that a suicide bomber has carried out an attack near a U.S. diplomatic site in the Red Sea city of Jiddah.

Okaz news website says the bomber died in the attack, and that no other deaths were immediately reported. The bomber was apparently headed in a car toward a mosque that is near the U.S. consulate in Jiddah. Most of the consulate's staff have reportedly moved offices to a new location.

Sabq news website reported that two security guards were wounded in the attack, which took place early Monday.

U.S. Embassy officials in Saudi Arabia and Interior Ministry officials could not be immediately reached for comment.

A 2004 militant attack on the U.S. consulate in Jiddah left nine people dead.
