What we know about Kilmar Abrego Garcia and MS-13 allegations

The case of Kilmar Abrego Garcia - a 29-year-old from El Salvador who was deported from the US in March - has prompted a legal showdown over the administration's immigration policy.

Judges all the way up to the US Supreme Court have ruled that Mr Abrego Garcia was deported in error and that the US government should help "facilitate" his return to his home in Maryland.

But the White House has accused Mr Abrego Garcia of being a member of the transnational Salvadorian gang MS-13, a designated foreign terrorist organisation, saying he "will never live" in the US again.
