“A suicide bomber targeted a security checkpoint in northwestern Pakistan on Wednesday, killing two soldiers, a policeman and a civilian, security officials said. It was the second attack to hit Pakistan in as many days. The bombing happened in North Waziristan, a district in Khyber Pakhtunkhwa province that borders Afghanistan and is a former stronghold of the militant Pakistani Taliban group, also known as Tehreek-e-Taliban Pakistan or TTP. A number of civilians were also wounded in the attack, according to Rehmat Khan, a local police official. No one claimed responsibility for the attack but suspicion is likely to fall on the Pakistani Taliban. In the last six months, the TTP has stepped up its attacks since it unilaterally ended a cease-fire with the Pakistani government, brokered by neighboring Afghanistan last year.”
