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.

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.

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.

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.

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.
