Venezuelan President Nicolas Maduro has demanded El Salvador release hundreds of Venezuelans who were deported from the United States, who he described as being “kidnapped,” after his Salvadoran counterpart earlier proposed a prisoner swap.

SAN SALVADOR, El Salvador (AP) — Salvadoran President Nayib Bukele proposed carrying out a prisoner swap with Venezuela on Sunday, suggesting he would exchange Venezuelan deportees from the United States his government has kept imprisoned for what he called “political prisoners” in Venezuela.

El Salvador President Nayib Bukele proposed a swap in which more than 200 Venezuelan migrants deported there from the US would be traded for the same number of political prisoners held by Venezuelan leader Nicolas Maduro.
