US embassy spokesman Alberto Rodriguez said no Americans were killed or seriously wounded in the attack, which killed one Pakistani and wounded 10 people. He said initial reports suggested it was carried out by a suicide bomber on a motorcycle.

The attack took place on a main road in an area where many Western diplomats live and involved 50 kg (110 pounds) of explosives, police said. "There was an attack on a two-car convoy from the consulate in Peshawar. One car was hit. We are still investigating what actually happened," said Rodriguez.

It was the first attack on Westerners since bin Laden's death.
