Venezuela has released 10 jailed U.S. citizens and permanent residents in exchange for getting home scores of migrants deported by the United States to El Salvador months ago under the Trump administration’s immigration crackdown.

Venezuela is set to receive a group of deportees freed from jail in El Salvador following an unexpected breakthrough in ongoing talks with the US.

El Salvador’s government sent more than 250 Venezuelans it was holding in a maximum-security prison to Caracas in exchange for 10 Americans detained by Venezuelan President Nicolás Maduro’s government, U.S. and Salvadoran officials said.
