After recent Pakistani military operations in Pakistan's own Swat Valley to push out Taliban insurgents who had taken control of the region, its operations are now more focused on the Taliban strongholds in the South Waziristan region. Pakistani troops and Taliban militants have been locked in intense clashes recently in the tribal area which has killed more than 150 people. Relief workers say that more than 120,000 people have been displaced by the fighting. Insurgent responses to the increased military pressure have included numerous bombings and suicide attacks, killing and injuring scores across Pakistan in recent weeks. Just today a car bomb in a busy marketplace in Peshawar killed more than 93 people, as U.S. Secretary of State Hillary Clinton made an official visit - announcing the latest in a series of U.S. aid packages to Pakistan.
