A suicide bomber has died in a blast opposite the US Consulate in Jeddah, Saudi Arabia, state TV reports.
Two security guards were said to be lightly injured after the man detonated a device in the Red Sea city in the early hours of American Independence Day (July 4).
The US State Department has confirmed all personnel are accounted for. It is working with the Saudi authorities to gather further details about the incident.
An eyewitness says police appeared to carry out at least three controlled explosions in the area, following the initial blast.
It is the first bombing in years to target foreigners in Saudi Arabia.
In 2004, militants attacked the Jeddah consulate, killing nine people.
