Pakistan Bombing Kills 4, Taliban Claims Responsibility VOA News May 25, 2011 Pakistani soldiers, police officers check a police building after it was attacked by a suicide bomber in an explosives-laden pickup truck in Peshawar, Pakistan, May 25, 2011 Photo: AP Pakistani soldiers, police officers check a police building after it was attacked by a suicide bomber in an explosives-laden pickup truck in Peshawar, Pakistan, May 25, 2011 A suicide bomber has rammed an explosive-laden vehicle into a building housing a police unit in northwestern Pakistan, killing at least four police officers. Police officials say the attack in the city of Peshawar on Wednesday left at least 28 people wounded. The blast destroyed the building. The Pakistani Taliban has claimed responsibility for the bombing. The militant group has carried out a string of attacks that it says are revenge for this month's killing of Osama Bin laden. The al-Qaida leader was killed by U.S. special forces during a raid in Pakistan. Prior to Wednesday's bombing, the Taliban had claimed responsibility for three other incidents, including a Monday attack on a Karachi naval base in which 10 security personnel members were killed. .
