Mexico’s government has formally objected to the United States sending Mexican nationals to Guantanamo Bay, Cuba, through a diplomatic note, President Claudia Sheinbaum announced on Tuesday.

The protest was issued after the Trump administration unveiled plans last month to transfer migrants to the U.S. naval base in Guantanamo Bay, a controversial detention site located on the Caribbean island.

In addition to opposing transfers to Guantanamo, Mexico has requested that all deported Mexican nationals be returned directly to Mexico rather than being sent to third countries, Sheinbaum emphasized during her daily press briefing.

"No Mexican should be sent anywhere but Mexico," she stated firmly.

Sheinbaum’s remarks follow the Trump administration’s recent deportation of over 200 suspected members of the Venezuelan Tren de Aragua gang to El Salvador, despite a court order prohibiting the move.

The American Civil Liberties Union (ACLU), which has challenged these deportations, has also sought to block the transfer of migrants to Guantanamo Bay, citing reports of harsh detention conditions and suicide attempts among detainees held at the facility.
