At least eight people -- including seven security officials -- were killed and 22 injured in a suicide attack at a police station in Bannu on Friday. The bomber struck 25 minutes after the suicide attack on the ISI building in Peshawar. A police official told Daily Times that a suicide attacker rammed his explosives-laden vehicle into the Bakkakhel Police Station on Miranshah Road -- killing seven security personnel, two FC troops and a pedestrian. The police official said 22 people, including 19 policemen, were also injured in the suicide attack. The station is close to the border with North Waziristan, an area in Pakistan's semiautonomous tribal region where officials believe many Taliban have fled to escape the recent army offensive. The bombings took place as US National Security Adviser Gen James Jones visited the country for talks with top political and security officials, including military chief Gen Ashfaq Kayani. The government has vowed the surging attacks would not dent the country's resolve to pursue the operation in South Waziristan.
