According to Charsadda police, four persons including two policemen were killed and several others injured when a suicide attacker detonated himself close to the hujra (guest room) of Asfandyar Wali Khan. NWFP Minister for Information Mian Iftikhar Hussain told APP that Asfandyar Wali Khan and his family members remained safe in the attack, however his bodyguard died. According to AFP, - A suicide bomber blew himself up as he tried to storm the house of a member of Pakistan's ruling coalition Thursday, killing four people but missing the politician, officials said. The bombing in the troubled northwestern town of Charsadda highlighted the threat posed by Taliban and Al-Qaeda militants to Pakistan's new government in the wake of the bombing of the Islamabad Marriott Hotel last month. It happened as Asfandyar Wali Khan, head of the Awami National Party (ANP), was visiting a guest in a room attached to his house during celebrations for the Muslim festival of Eid al-Fitr, police and party officials said. "Four people were killed in the suicide blast. The target was Asfandyar Wali but he is safe," Mian Iftikhar, the information minister for North West Frontier Province, told local television. Provincial police chief Malik Naveed told AFP that guards shot the bomber before he blew himself up. "The suicide bomber tried to pass from the security scanner avoiding a physical search. Two security guards grabbed him but he tried to get away," Naveed said. "Then he was shot and as soon as he fell on the ground he blew himself up."
