Afghan Refugees Make Long Trek Home

Pakistan in April began closing its largest camp for Afghan refugees out of fear that remnants of the Taliban were using it as a hideout. Now, more than 70,000 Afghans are being uprooted once more and many are making the dangerous journey back to their homeland. From war widows and teenagers to young families, they are on the move, hoping to rebuild their lives in a country many have not seen for decades. Mandy Clark visited the Afghan-Pakistan border, where many of the returning refugees pass on their way back home.
