U.S. immigration and military authorities say they have transferred exclusively Venezuelan immigrants who are subject to final deportation orders to the U.S. naval station at Guantanamo Bay, Cuba.

Nearly 200 illegal migrants being held by the US in Guantanamo Bay have been flown home to Venezuela — the latest mass deportations since the South American nation backed down from refusing to accept them.

A U.S. defense official confirmed to VOA that a C-130 military cargo plane carrying migrants left Fort Bliss in Texas and arrived at Guantanamo Bay on Sunday. A second defense official said all 17 migrants were assessed to be “high threat” and are being held at the base’s detention facility.

Nearly 200 Venezuelan migrants to the U.S. were returned to their home country after being detained at Guantanamo Bay, in a flurry of flights that forged an unprecedented pathway for U.S. deportations.
