Pope Francis has issued an appeal on behalf of Cuban migrants stranded in Central America. In his Angelus address on Sunday, the Pope called for a "rapid solution" to the "humanitarian drama" involving an estimated 5,000 Cubans seeking to enter the United States overland. According to Vatican Radio, Pope Francis said: “My thoughts in this moment go out to the numerous Cuban migrants who find themselves in difficulty in Central America, many of whom are victims of human trafficking. "I invite the countries of the region to renew with generosity all necessary efforts in order to find a rapid solution to this humanitarian drama.” The migrants are currently stranded at the border between Costa Rica and Nicaragua after Nicaraguan officials refused to allow them to enter the country. Migration is likely to be a major theme of Pope Francis's visit to Mexico on February 12-18.
