A bomb tore through a busy market in Pakistan’s tribal belt on Thursday, killing at least nine people, including two children, near the Afghan border, officials said. Twenty others were wounded when the device, planted in a pick-up truck, exploded in Pasht bazaar of Salarzai in Bajaur district, one of the toughest battlegrounds in Pakistan’s fight against the Taliban in the northwest. “There are nine bodies and 20 wounded brought to hospital,” Doctor Khalilur Rehman said. Two children aged eight and 13 were among the dead and four children aged five to 11 were among the injured, he said. A government official had earlier put the death toll at five. Nobody claimed the responsibility for the bombing, but the Taliban have carried out several attacks against Salarzai tribesmen for forming pro-government militias and supporting military operations. According to a tally, around 5,000 people have been killed in militant attacks across the country since July 2007, when government troops raided an extremist mosque in the capital Islamabad, sparking a bloody insurgency.
