Members of Venezuela’s most feared gang could be deported by the US to prison in El Salvador under a deal sought by President Donald Trump.

The Trump administration is in talks with El Salvador to accept citizens from other countries, including Venezuelan gang members from Tren de Aragua.

Built to house El Salvador's most dangerous gangsters, conditions at the maximum-security "Terrorism Confinement Center" (CECOT) are slammed by rights groups as inhumane.

The arrangement, known as a "Safe Third Country" agreement, would empower U.S. immigration officials to deport non-Salvadoran migrants to El Salvador.
