Officials say gunmen have kidnapped a Pakistani working on a US-funded aid project in the country's volatile northwest. Police said the attackers seized the man from a convoy of relief vehicles in the Dir region on Monday. Other aid workers escaped after villagers fired on the attackers. The UN's World Food Program said the victim was distributing wheat and cooking oil on its behalf. WFP spokesman Amjad Jamal said the food was paid for by the US government. Jamal said it was unclear if Taliban militants were behind the kidnapping and that WFP had received no demands.
