Nearly 200 Venezuelan immigrants 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.

A plane carrying more than 170 Venezuelan migrants who were held in Guantanamo Bay after being deported from the US arrived in Venezuela on Thursday, according to CNN sources.

The U.S. government and a Venezuelan state airline flew 177 Venezuelan migrants from Guantanamo Bay to Honduras and on to Venezuela on Thursday, U.S. Immigration and Customs Enforcement and the Department of Homeland Security said.

The US government flew 177 deportees from Guantánamo Bay to Honduras on Thursday. US border protection agency ICE said the deportees were then picked up and returned home by the Venezuelan government.

Officials at the Department of Homeland Security and the Defense Department are racing to set up multiple tent facilities in Guantanamo Bay, Cuba, to house thousands of migrants, but the scattered efforts have prompted questions internally about who’s in charge and what will happen once people arrive on site.

DHS said Venezuelan migrants who had been detained at the Guantánamo Bay Naval Station have been flown to Honduras and will be transferred next to Venezuela.

The Trump administration has flown all of the migrants it had held in Guantánamo Bay out of the facility there, NBC News has learned from three sources familiar with the operation and flight data.

Immigration and Customs Enforcement (ICE) officers have removed deported migrants from a facility on the U.S. military base in Guantánamo Bay, Cuba, where the Trump administration brought them as part of an effort to remove certain immigrants from the U.
