Two car bombs exploded in a failed suicide assassination attempt on Pakistani President Pervez Musharraf. Authorities say the blasts killed at least six people and injured at least two.

The attack occurred in Rawalpindi, next to the capital Islamabad, as President Pervez Musharraf's motorcade passed along a street closed to other traffic.

Army spokesman Major General Shaukat Sultan Khan says the two cars carrying the bombs sped out of a gas station, and one hit the motorcade.

"The last vehicle of the presidential convoy, which had the police escort got hit and got damaged," he announced. "The police escort inside got injured, but the president and his entire staff is absolutely safe."

In addition to killing several passersby, the attack also damaged surrounding buildings.

It is the second attack on President Musharraf this month - on December 14, he escaped another bomb aimed at his convoy, just 500 meters away.
