No group has claimed responsibility for the attack yet. However, Pakistan’s Taliban had vowed to increase attacks ahead of the general elections in May 2013.
Bajaur is part of the Pakistan’s Federally Administered Tribal Areas (FATA) in the country’s northwest region bordering Afghanistan, where the Taliban, Al-Qaeda and other militant groups have a strong presence. The Pakistani army has launched several offensives against the militants in the region since 2008, flushing out most of the militant leaders from the province.
More than 3,000 Pakistani security personnel have been killed in the anti-militant operations.
However, the militant groups have continued their attacks unabated, from across the border villages in Afghanistan.
Despite undertaking several counter-insurgency measures against the militants, Pakistan’s military has failed to reign in extremist groups backed by the Al-Qaeda and the Taliban, which has stepped up attacks in the wake of the May general elections.
