Secret US deportation deals send shackled migrants to countries they never chose

A Guardian investigation found thousands deported from the US under shadowy deals with dozens of countries. On one flight, 18 shackled migrants learned from seat-back maps they were bound for Central African Republic; officers had taunted them about their destination. Nika, an Iranian woman who fled protests and spent over a year in US detention, was among them. The operations cost American taxpayers millions.
