Suicide bombers hit a bus carrying intelligence agency employees and a checkpoint near the headquarters of the Pakistan army today, killing at least 35 people.

The two attackers struck in Rawalpindi, a garrison city just south of the capital, Islamabad. A senior intelligence official, who asked for anonymity because of the sensitivity of his work, said at least 35 people were killed.

In the first attack, an explosive-laden car rammed a bus carrying employees from the Inter-Services Intelligence agency, while the other bomber hit the checkpoint, said Mohammed Afzal, a local police official.

The violence comes as Pakistan remains under a state of emergency, a move by President Gen. Pervez Musharraf that has prompted stiff criticism of the military ruler, including from his key Western ally, the United States.
