CNN:

U.S. and Saudi officials said they suspect al Qaeda in the explosions, which tore through three compounds housing Westerners in Riyadh. Saudi officials said the assailants shot their way into the upscale, gated communities before setting off their explosives-laden vehicles in suicide attacks.

UPDATE:

Guardian is reporting at least 50 are dead:

Between 40 and 50 people were feared dead today after a series of suicide bomb explosions rocked the Saudi capital, Riyadh, overnight. "It seems we have lost 10 Americans killed, many other nationalities were also killed," the US secretary of state, Colin Powell, told reporters as he arrived at Riyadh airport earlier today, within hours of the devastating attacks. "Terrorism strikes everywhere and everyone. It is a threat to the civilised world," he said.

One Australian man was also killed and another injured in the four bomb blasts that ripped through foreign housing compounds, according to the Australian government.

A Danish newspaper quoted Niels Joergen Secher, a Danish doctor at Riyadh's King Faisal hospital, as saying between 40 to 50 bodies were brought to his hospital.

UPDATE:

From Sky News:

Unconfirmed reports say the son of Riyadh's deputy governor Abdullah al-Blaihed, an Australian, a Lebanese man and two children are among the dead...

...The London-based Arabic magainze Al-Majallah said al Qaeda had implied it was behind the attack.

A fourth explosion targeted the headquarters of Siyanco - a joint US-Saudi-owned company.

In a new departure in terrorist attacks, one eyewitness told Sky News Online that two gunmen shot at the wounded as they stumbled from the bombed out wreckage of the Al Hamra compound.

Momen Abu Tair, 34, said there were two trucks - the suicide bombers had tied themselves to the inside of one of the vans - while two gunmen were travelling in a second vehicle.
