Reporter's Notebook: Families Fleeing Afghanistan Struggle to Survive in Turkey

VAN, TURKEY - Afghan clothes and Iranian SIM cards litter fields under the mountains that stand between Turkey and the Iranian border. 

A wisp of smoke rises out of what was a small fire, abandoned many hours before.   As the Taliban swept through villages and cities in Afghanistan over the past few months, families have fled in droves, many traveling across Iran and into Turkey.   In the past, this route was flooded with refugees trying to get to Europe to seek safety and freedom. Now it's packed with people making a last-ditch effort to stay alive in Turkey, where they find no humanitarian aid and run the risk of being arrested and deported.
