The group of alleged violent criminals tied to Tren de Aragua and MS-13 was transported by the US military on Sunday night, US secretary of state Marco Rubio said in a statement, adding that the deportees included murderers and rapists.

El Salvador’s President Nayib Bukele said in a post on X that all deportees were “confirmed murderers and high-profile offenders, including six child rapists.”

US authorities did not provide names of individuals or details about the alleged convictions. The state department and US department of homeland security did not immediately respond to requests for comment.

Trump, a Republican, took office in January vowing to deport millions of immigrants in the US illegally as part of a wide-ranging immigration crackdown. Earlier this month, Trump invoked the Alien Enemies Act, an 18th-century law that historically has been used only in wartime, to target alleged members of the Venezuelan gang Tren de Aragua.

The American Civil Liberties Union challenged Trump’s use of the law, saying it denies the migrants the due process promised by the US Constitution to contest the basis for their removal. Family members of some of those deported have denied that they have gang ties.

A US federal appeals court last week upheld a lower court’s block on Trump’s use of the law to rapidly deport alleged gang members. The Trump administration has said it would continue to use other legal authorities for deportations. Rubio did not say which authorities were used for Sunday’s deportations.

The Trump administration has asked the US Supreme Court to lift the halt on Trump’s use of the law.
