Nato supply trucks, bearing registration No 9496 and 9351, were on their way to Torkham border from Peshawar to deliver the assignment somewhere in Afghanistan when unknown armed persons intercepted them and opened fire on them. As a result, three crew members of the trailers got wounded, sources said. The injured were rushed to a nearby health centre where two of them succumbed to their injuries while the third was referred to Hayatabad Medical Complex in view of his precarious condition.Shortly after the incident, the Khasadar Force personnel moved to the site and compelled the militants to flee in cross firing. The deceased were identified as Atiqur Rehman son of Noor Zaman, a resident of Rahim Yar Khan, and Alam Sher s/o Shad Muhammad of Vehari.The security forces and Khasadars, in a joint search operation in the area, detained 15 suspected persons who were sent to Jamrud lockup for investigation.It is important to mention here that the Nato supply route via KPK through Khyber Agency remained suspended for almost three months because of the sit-in of Pakistan Tehreek-e-Insaf (PTI) workers.
