El Salvador has agreed to house violent US criminals and receive deportees of any nationality, US Secretary of State Marco Rubio announced Monday, in an unprecedented – and legally problematic deal – that has alarmed critics and rights groups.

U.S. Secretary of State Marco Rubio says El Salvador's president has offered to accept deportees from the U.S. of any nationality, including Americans.

Secretary of State Marco Rubio praised President Nayib Bukele’s “unprecedented, extraordinary” proposal to accept any convicted criminal deported by the United States.
