Ten die in Riyadh bombing

At least 10 people were killed and dozens wounded today when a car bomb destroyed a Saudi security service building in the capital, Riyadh.

Saudi officials described it as a "terrorist attack" and Arab television said the body of suicide bomber had been found.

The kingdom, a key U.S. ally and the world's largest oil exporter, is battling a tide of Islamist militancy linked to Saudi-born Osama bin Laden's al Qaeda network.

Last year, suicide bombings at foreign residential compounds in Riyadh killed 50 people.

Ambulances rushed toward the site of Wednesday's blast and smoke billowed from damaged buildings in the area, which also houses state television and the Information Ministry.

Last week five cars rigged with explosives were defused by Saudi bomb disposal experts.
