There are currently more than 87,000 applications for refuge in Costa Rica, of which 80% are from Nicaraguans and 7% are from Venezuelans, according to government data.

The US Secretary of State, Mike Pompeo, said in a statement that he informed Congress of his intention to resume foreign aid for El Salvador, Guatemala and Honduras.
