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.

A transfer operation on Thursday repatriated 177 Venezuelans via a handoff in Honduras, while one migrant was brought back to U.S. soil.

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.

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 said little about the Venezuelan men who were transferred from Texas to the U.S. military base in Cuba.
