Pakistani Taliban gunmen disguised in burqas stormed a provincial government complex for agricultural research in northwest Pakistan on Friday, killing 12 people including students and wounding 35 others, police and rescue officials said. Police and military troops summoned to the scene killed three attackers at the Agriculture Training Institute in the city of Peshawar, the capital of Khyber Pakhtunkhwa province, about two hours into the attack, the militarys press wing said. The Pakistani Taliban claimed responsibility, saying in a message from spokesman Mohammad Khorasani that they had targeted a safe house of the militarys Inter-Services Intelligence agency. The gunmen arrived at the campus in an auto-rickshaw, disguised in the burqas worn by many women in the region, Peshawar police chief Tahir Khan said. They shot and wounded a guard before entering the campus, he said. The Pakistani Taliban later released a video showing the attack, recorded with what appeared to be a body-mounted camera. In it, one of the gunmen raced into a building shouting "Allahu Akbar!" and firing his weapon as he went room to room searching for students. The militants also issued photos of the attackers, who they said were from nearby Swat Valley, singing with the movements fugitive leader, Mullah Fazlullah, before their mission. Shehzad Akbar, medical director of Hayatabad Medical Complex, said six people died of their wounds and 18 were being treated. Another three people died at Khyber Teaching Hospital and 17 wounded were there, director Nekdad Afridi said. In December 2014, Pakistani Taliban gunmen killed 134 children at Peshawars Army Public School, one of the single deadliest attacks in the countrys history. The Pakistani Taliban are loosely allied with the Afghan Taliban insurgents who ruled most of Afghanistan until they were overthrown by US-backed military action in 2001.
