Taliban group Jamaat-ul-Ahrar claimed responsibility for the bombing. Last month, the United States designated JuA a global terrorist organization, saying the group has staged multiple attacks on civilians, religious minorities, military personnel and law enforcement . Local residents and tribal police helped ferry the wounded to hospital. An army helicopter was being used to transport the critically wounded to Peshawar, the main city in northwestern Pakistan. Friday’s attack came hours after army chief Gen. Raheel Sharif met with Prime Minister Nawaz Sharif to discuss security issues. He pledged to continue the war against terrorism. Some 18,000 civilians and 5,000 soldiers have been killed in militant attacks in Pakistan since 2001, when Islamabad threw its support behind Washington in the war on terror.
