Government struggles to handle flood of migrants
The central government is trying to come to grips with the new flood of migrants who are entering the country illegally at the rate of from 100 to 150 a day.
Casa Presidencial said Wednesday that the Fuerza Pública would reinforce the country’s southern border with Panamá. The government also revealed that up to 80 percent of the migrants who hope to reach the United States are not Africans, as was thought. They are Haitians, said a government summary. However, there are migrants from Somalia, Iraq and Afghanistan as well as the Congo, Ghana, the Ivory Coast, Guinea, Togo, Nepal, Bangladesh, Burkina Faso, India, South Africa and the Sudan.
