Human rights advocates warn that the deportees legal rights were violated as they were transferred to the CECOT, a mega-prison established by El Salvador’s President Nayib Bukele for his crackdown on gangs in the country. The facility, according to the Associated Press, can hold up to 40,000 inmates; up to 70 people are housed in a single cell.

More than 200 alleged Venezuelans gang members have been deported from the US to a supermax prison in El Salvador by the Trump administration, despite a court order forbidding it.
