A bomb destroyed a hotel in the center of this northwestern frontier city Saturday and killed 13 people, police said. Officials blamed government agents from neighboring Afghanistan.

Devout Moslems had just finished morning prayers shortly after sunrise when the bomb exploded, tearing through the three-story hotel and tearoom in the old section of the city, said Abdul Ahmed Khan, assistant inspector of crimes."It collapsed just like a sandwich," said Khan.

Rescuers pulled out the bodies from the ruins of the hotel. Two people survived nine hours under the rubble but died on the way to the hospital, police said.

Police said they suspected that agents of Afghanistan's Communist government were responsible for the blast.
