PESHAWAR: The US Federal Bureau of Investigation will lead the probe into a suicide car bomb attack on an American diplomatic car in Pakistan that killed two people, officials said Wednesday.

The FBI team will work alongside Pakistani investigators as they search for clues to who was behind Monday's blast in the northwestern city of Peshawar, in which an attacker rammed his explosives-laden car into US consulate vehicle.

Two American and two Pakistani consulate employees were wounded in the bombing, the deadliest attack targeting Americans in the country in more than two years.

No group has yet claimed responsibility, but militants linked to the Taliban and al-Qaeda have targeted the consulate and its staff at least twice before since April 2010.

“An FBI team is leading the investigation of the Peshawar blast on behalf of the US government. We are closely coordinating with the Pakistan government,” a US official in Peshawar told AFP, confirming what US State Department spokesman Patrick Ventrell told reporters in Washington on Tuesday.

FBI agents have arrived in Pakistan and will work with Pakistani counterparts to inspect the blast site and vehicles damaged in the explosion, diplomatic sources said.
