Reporting from Islamabad and Peshawar, Pakistan — Suicide bomb blasts tore through a busy market in a volatile tribal region along the Afghan border Friday, killing more than 65 people in an attack that illustrated the Taliban insurgency's potency despite several recent offensives carried out by Pakistani troops against militants in the country's tribal belt. The explosions took place in the village of Yaka Ghund in the Mohmand tribal region, outside the offices of a senior Mohmand administrator, police said. At least 112 people were injured. Authorities said one of the bombers was on a motorcycle, while the other detonated a Toyota Corolla sedan filled with explosives. The intended target remained unclear. A large crowd lining up for new national identity cards had gathered at government offices in Yaka Ghund's main bazaar, and the bazaar itself was filled with midmorning customers. Government offices and bustling markets have often been targeted in Taliban suicide bomb attacks.However, Pakistani television channels reported that members of a local lashkar, or anti-Taliban tribal militia, had been meeting in the vicinity when the blast occurred and may have been the intended target.
