No clues yet on WFP attack

ISLAMABAD, Pakistan, Oct. 7 (UPI) -- Pakistani investigators haven't found any clue yet in the suicide blast at the World Food Program office that killed five people, sources told the Daily Times.

The attack on the WFP office in the highly guarded area of sector F-8/3 in Islamabad occurred Monday. Those killed included four Pakistani staff members and one Iraqi national.

The Pakistani Taliban Tuesday claimed responsibility for the attack and its spokesman, Azam Tariq, told reporters by telephone from an undisclosed location the militants plan to target more such foreign aid agencies in Pakistan, the Voice of America reported. Tariq said agencies like the WFP promote what he said was a Western agenda in the country.

A joint investigation team headed by a deputy inspector general, which is looking into the blast, said authorities have collected phone call data and were decoding them, the Daily Times report said.

Earlier reports said the attacker wore a security personnel uniform but the Times report said investigators were still trying to determine how he managed to enter the tightly secured area.

The VOA quoted Pakistani Interior Minister Rehman Malik as saying he believed the Taliban attacked the WFP in retaliation for the death of their former leader Baitullah Mehsud, who was killed in August in a suspected U.S. missile strike.
