QUETTA (Agencies) - Making sure nothing sensitive is left behind, American forces set on fire all their redundant and useless equipment before abandoning the Shamsi airbase. A military official in Balochistan termed the burning of equipment by the US as a routine practice as the gear was no longer required. The last flight carrying US personnel and equipment had departed from Shamsi airbase in Balochistan province on Sunday and the facility had been completely vacated by the Americans, the ISPR had said.
