Suicide Bomber Kills 4 in NW Pakistan VOA News 28 April 2010 Pakistani security officials survey a crater at the site of a suicide bombing at a checkpoint on the outskirts of Peshawar, Pakistan, 28 Apr 2010 Photo: AP Pakistani security officials survey a crater at the site of a suicide bombing at a checkpoint on the outskirts of Peshawar, Pakistan, 28 Apr 2010 Police in northwestern Pakistan say a suicide car bomber has killed four police officers and wounded at least eight other people. Local authorities say the attacker blew up his explosives-laden car early Wednesday on the outskirts of Peshawar, the capital of Khyber Pakhtoonkhaw province. The blast came a day after Pakistani security forces killed 11 militants in clashes in nearby Orakzai tribal region. Pakistan's military launched an anti-Taliban offensive in Orakzai in March to target militants who are believed to have fled an earlier offensive in South Waziristan. In other violence, gunmen killed a university professor in a drive-by shooting in Quetta, the capital of southwestern Baluchistan province. Â .
