A bomb blast killed at least 16 people, including women, and wounded 30 others on Friday on the outskirts of Pakistan's northwestern city of Peshawar, police said. The explosion went off in the Daudzai area near a bus carrying government employees, senior police official Tahir Ayub told AFP. Another senior local police official Dilawar Bangash confirmed the new death toll. The attack came one day after a remote-controlled bomb killed at least 15 people outside a madrassa in Pakistan's southwestern city of Quetta. Pakistan sits on the frontline of the US-led war on Al-Qaeda and since July 2007 has been gripped by a local Taliban-led insurgency, concentrated largely in the northwest. In the last five years, attacks blamed on Islamist bombers have killed more than 5,000 people, according to an AFP tally. Its relations with the United States are in disarray and for the last six months, Pakistan has imposed a blockade on NATO supplies crossing overland into Afghanistan since US air strikes killed 24 Pakistani soldiers along the border.
