The first group from among 8,000 Cubans stuck in Costa Rica — because Nicaragua won't let them continue their journey to the US — are due to fly to El Salvador in January, from where they will be transported by bus to Mexico.
Thousands of Cuban migrants heading for the United States have been stranded in Costa Rica since Nicaragua closed its border to them in mid-November and other regional governments have rejected proposals to provide them with safe passage north.
The migrants were following the increasingly popular route of flying from Cuba to Ecuador and then travelling north by land to the US border, but their way has been blocked by Nicaragua refusing to let them through.
Over 1,000 Cubans migrants have been stuck in Costa Rica since Sunday when Nicaragua shut the border to them. The numbers keep growing as ever more Cubans arrive at the bottleneck spurred by fears of imminent changes to their special immigration status.
