PESHAWAR At least four persons including a policeman were killed and five others got injured on Monday when a suicide bomber blew himself up near a police checkpoint here on Ring Road. Police and eyewitnesses informed TheNation that the suicide bomber got out of a rickshaw and detonated his explosives. As a result, a policeman, rickshaw driver and two passers-by died on the spot. Chief of Capital City Police, Liaquat Khan, while talking to media persons told that the checkpoint was not the actual target of the bomber and he was in search of some crowded place but the brave policeman Waheedullah thwarted his bid. Soon after the blast, the rescue teams rushed towards the site and shifted the dead and the injured to Lady Reading Hospital. The deceased included Dilawar, rickshaw driver, Sotar Khan son of Abdul Rehman, and police constable Waheedullah son of Shah Afzal. The bomb disposal squad collected evidences from the blast site and, according to them, about six kilogram explosive material was used in the attack. Waheedullah was recently recruited in police force and he had also served in Pak Army. His funeral prayer was offered in Police Line, which was attended by NWFP Inspector General of Police and other high-ranking officers. It is sad to mention here that it was the second suicide attack within a period of 24 hours in Peshawar. The earlier attack on Sunday was engineered against former UC nazim Adezai, Haji Abdul Malik, who was leading a lashkar against militants in Matni area. Meanwhile, President Asif Ali Zardari, Prime Minister Syed Yousuf Raza Gilani, NWFP Governor Owais Ahmed Ghani, Chief Minister Ameer Haider Khan Hoti and NWFP Information Minister Mian Iftikhar Hussain strongly condemned the suicide attack. They expressed deep sorrow over the casualties and prayed Allah Almighty to shower His blessings on the departed souls. They also directed best possible medical treatment for the injured. They termed the attack as barbaric and said the government would continue efforts to wipe out extremists and terrorists from the country. Both President Zardari and PM Gilani expressed their resolve not to be deterred by acts of violence. Agencies add: The driver stopped his (the bombers) rickshaw at the checkpoint and a police constable asked him to get out but he appeared reluctant, policeman Asmatullah Khan, who watched the attack from behind sandbags, told AFP. The constable tried to drag him out. He blew himself up soon after stepping out of the vehicle. The rickshaw driver also died. Officials said four people were killed - a policeman and three civilians - while five others sustained injuries. The blast destroyed two vehicles, left the rickshaw a mangled wreck, damaged a police van and splattered blood on the road at the small checkpoint, where police had erected barricades to search cars, an AFP reporter said. Suicide attacks and bombings frequently strike the sprawling city of 2.5 million people. In the deadliest attack in Pakistan in two years, a massive car bomb killed 118 people in a Peshawar market on October 28. Doctor Zafar Iqbal at the citys main government-run Lady Reading Hospital said four bodies, including that of the bomber, were brought to the morgue.
