Pakistani Taliban has claimed responsibility for an attack by a woman suicide bomber on the World Food Programme centre in the volatile tribal belt that killed 46 people. Tehrik-e-Taliban Pakistan spokesman Azam Tariq claimed responsibility for Saturday's attack at Khar, the headquarters of Bajaur tribal region. The bombing killed 46 people and injured over 80 others. In the first attack of its kind, the woman bomber struck at a time when some 600 people had gathered at the centre to receive aid. The food distribution center temporarily stopped its operations in the region. Tariq said the attack was directed against members of the Salarzai tribe because they had supported the army against Taliban. He said, the Salarzai tribe had formed a 'lashkar' or militia against Taliban and that is why they were targeted.
