ISLAMABAD, Pakistan (AP) – A small bomb exploded Friday in an industrial city of eastern Pakistan, wounding 18 people, mostly children, and shattering windows, a senior police official said.

The blast occurred in Faisalabad, 165 miles south of the capital, Islamabad, said Abid Saeed, a deputy inspector general of police.

He said the bomb had been left in a street. The motive for the attack was not clear.

Another police official in Faisalabad, Nasrullah Khan Niazi, said investigators collected pieces of a bomb that appeared to be a booby trap.

He said three of the victims were seriously hurt when they were hit by pieces of flying metal. The explosion shattered windows at two homes.

The city of Faisalabad is known mainly for its textile mills.
