Dahud Hanid Ortiz, a former U.S. Marine convicted of a triple homicide in Spain, was among 10 Americans repatriated in exchange for 250 Venezuelans held in El Salvador.

Forty-eight Venezuelans detained by their own government have so far been released under the terms of a prisoner exchange agreed with the United States, legal rights advocacy group Foro Penal said on Monday.

Ten Americans and permanent U.S. residents detained in Venezuela were traded for more than 250 Venezuelans expelled from the U.S. and imprisoned in El Salvador.
