Tehreek-e-Taliban Pakistan (TTP) has claimed responsibility for the suicide bomb attack on a mosque in northwest Pakistan, which left 56 people dead, local English newspaper Daily Times said on Sunday. According to the report, a spokesman of TTP\'s Tariq group called a local reporter on Saturday to claim responsibility for the suicide attack. The spokesman named Talha alleged that the Koki Khel tribe had contrived against their group in Mehraban village of Tirrah Valley. That was why their members were targeted in the Ghondi mosque in Jamrud, he said. \"A lashker (civil militiaman) of Koki Khel tribe has killed our fighters in Tirrah Valley and has demolished the houses of our members,\" said the spokesman, adding that more actions will be taken against the members of Koki Khel tribe if they continue to resist TTP in Tirrah Valley. On Friday afternoon, a teenage suicide bomber broke into a mosque through a window in the Ghondi area of Jamrud in northwest Pakistan and blew himself up among hundreds of Friday prayers, killing 56 people and injuring over 100 others.
