Pakistan Arrests 35 for Bombing of US Troops VOA News 04 February 2010 Site of school bombing in Pakistan Photo: AP A boy is seen through a damaged window of a school at the site of Wednesday's roadside bombing in Shahi Koto, a village of Pakistani district Lower Dir, 04 Feb 2010 Pakistani officials say they have arrested 35 suspects in connection with a bombing that killed three American soldiers in northwest Pakistan. Police official Naeem Khan said Thursday Pakistani police are questioning the suspects to determine who orchestrated the suicide attack. Officials said the Wednesday blast that also killed four Pakistanis was caused by a car bomber and not a roadside bomb as earlier reported. Three of the Pakistani victims were schoolgirls, and the fourth was a local soldier. More than 60 others were wounded in the blast. The three Americans killed in the attack were military personnel traveling to the opening ceremony of a girls' school that recently was renovated with U.S. assistance. Pakistan's Taliban later claimed responsibility for the bombing. District police officer Mumtaz Zareen told VOA that militants exploded the bomb just as the soldiers' convoy passed the school in the Lower Dir district near Swat Valley, a well-known former stronghold of the Taliban. A statement from the U.S. embassy in Islamabad said the American military personnel were part of an ongoing training program with paramilitary troops in the northwest. Pakistani and U.S. officials have condemned the attack. U.S. Special Representative to Pakistan and Afghanistan Richard Holbrooke said U.S. officials do not believe the American trainers were directly targeted. He also rejected Taliban claims that the men were employees of the Blackwater security firm, and said he expects officials will release the identities of the dead after their families are notified. No U.S. combat troops are officially stationed in Pakistan. U.S. and Pakistani officials say the American military personnel were part of a small unit training soldiers of the paramilitary force known as the Frontier Corps to better fight al-Qaida and Taliban militants.
