Insurgents mounted a brazen assault on the Saudi ruling family’s security network Wednesday, setting off car bombs outside the hulking Interior Ministry building and a guard training center in the capital and then exchanging gunfire with police.

The blasts in Riyadh came two weeks after the release of an audiotape believed to have been recorded by Osama bin Laden decrying the Saudi royal family as “corrupt Zionists” and calling for Muslims to topple the kingdom’s government.

The taped message called for attacks on the Saudi oil industry; after Wednesday’s assault, the price of oil surged by nearly $2 a barrel.

The blasts and gunfire, which left at least 10 people dead and 17 wounded, erupted a day after Saudi forces raided a suspected militant hide-out in Riyadh. They killed at least three gunmen and rounded up suspects as part of an ongoing crackdown against the insurgency.

Wednesday’s strikes began at the Interior Ministry, where a remote-control car bomb went off inside a traffic tunnel leading to the complex, killing a passing driver. Less than 30 minutes later, a pair of suicide bombers blew up a car outside the training facility on the main Riyadh thoroughfare of King Fahd Street, Saudi sources said.

Seven gunmen were shot to death a short time later when security forces stormed a villa on the northern outskirts of the city. The government said the house was a hide-out for those who plotted the attacks, and vowed to continue their hunt for the militants.
