Afghan forces guard Bagram airbase

Afghan security personnel were seen guarding Bagram Airbase on Monday (July 5), after American troops left their main military base in Afghanistan, marking a symbolic end to the longest war in U.S. history. The quiet departure from Bagram Airbase on Friday (July 2) came as the Taliban insurgency ramps up its offensive throughout the country after peace talks sputtered. Emer McCarthy reports.
