Colombia's armed conflict has forced millions of people to flee their homes, including hundreds of thousands who have sought refuge in other countries in the region.
Along the border with Colombia, Panama's Darien region is a thick and inhospitable jungle accessible only by boat. Yet many Colombians have taken refuge here after fleeing the irregular armed groups who control large parts of jungle territory on the other side of the border.
Many of the families sheltering in the Darien are from Colombia's ethnic minorities – indigenous or Afro-Colombians – who have been particularly badly hit by the conflict and forcibly displaced in large numbers. In recent years, there has also been an increase in the numbers of Colombians arriving in the capital, Panama City.
There are an estimated 12,500 Colombians of concern to UNHCR in Panama, but many prefer not to make themselves known to authorities and remain in hiding. This "hidden population" is one of the biggest challenges facing UNHCR not only in Panama but also in Ecuador and Venezuela.
