In this July 3, 2012 photo, Cuban migrant Mayra Reyes, sitting fourth from right, gathers with other Cubans with whom she traveled as they rest at a shelter along with another group of migrants from Bangladesh, after being found by Panamanian border police in the Darien province in Meteti, Panama. Panamanian authorities began noticing five years ago that the Darien Gap, the only interruption in the Pan-American Highway, was being used by migrant smugglers, usually to move people from Asia and Africa. Panama's Public Safety Minister Jose Murillo says that the movement of people from Asia and Africa has tapered off but that hundreds of Cubans are now taking the arduous Darien Gap route toward the United States.
