Police say gunmen in southwestern Pakistan have torched two tankers carrying fuel for U.S. and NATO forces in Afghanistan, as AP reported. Two drivers of the tankers were also wounded in the two separate attacks on Friday in Baluchistan province. Police official Abdul Zahoor says one tanker was attacked in the Qilat area, where gunmen over the weekend burned 14 NATO tankers. The other tanker was hit in the Mastung area. Militants and criminals in Pakistan frequently attack trucks carrying supplies for U.S. and NATO troops. The supplies first arrive in Pakistan's southern port city of Karachi and from there they travel overland to neighboring Afghanistan. The U.S. is relying more on other routes, including through Central Asia, due to security concerns in Pakistan.
