A suicide bomber attacked a police checkpoint in the Pakistani city of Peshawar on Saturday, killing 10 people. The blast comes one day after a car bomb killed 17 people in the city. Like other attacks in the region, they are a response to the increased pressure by Pakistan's military to force the Taliban out of the South Waziristan region. The Taliban has claimed responsibility for both bombings. The military says it has killed more than 500 militants in South Waziristan, however, accounts have not been confirmed by independent observers.
