A Cuban migrant lights a candle as she prays to Santo Nino de Atocha at the Costa Rican border with Nicaragua November 18, 2015. Costa Rica proposed a "humanitarian corridor" for Cuban migrants transiting Central America on their way to the United States. Some 2,000 Cuban migrants are at the northern border with Nicaragua, and some 300 Cubans are expected to arrive at Costa Rica's southern border with Panama every day. REUTERS/Oswaldo Rivas
