Authorities initiated on Feb. 4 near-daily flights from a U.S. Army base in West Texas to Guantanamo. Fifty-one of the newly arrived immigrants are being held in low-security tent facilities, while 127 more are confined to a high-security area.

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 court filing by U.S. Justice Department attorneys says nearly 180 people are being held in tents and high-security facilities there.
