Pak arrests 35 suspected to be involved in Wednesday's bomb blast which killed three US soldiers also

Islamabad: Pakistani officials say, they have arrested 35 suspects in connection with yesterday's bombing that killed three American soldiers in northwest Pakistan. Police official Naeem Khan said the police are questioning the suspects to determine who orchestrated the suicide attack.

Officials said, the 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.
