Rahim Mohamed, 32, was already dreading being deported from his home of 15 years in Atlanta to Somalia, a country he hadn’t seen since he was a teenager. His dread transformed into a nightmare when he was chained to a seat on a plane for 46 hours with 91 other Somalis who say they were denied adequate food, water, medication, and even access to a restroom.

Allegations of mistreatment is the latest turn for the ill-fated flight, chartered last week by Immigration and Customs Enforcement to return Somalis to Somalia, one of several Muslim-majority countries named in the Trump administration’s controversial travel ban. It’s unclear how many were undocumented or targeted for another reason, but some onboard had lived here for decades and were slated for eventual deportation because of improper entry into the country, according to the New York Times.

The flight to Mogadishu left the U.S. last Thursday but was grounded in Dakar, Senegal, where the Somalis were confined on the hot plane on the tarmac for hours before returning to the U.S. under mysterious circumstances.

The would-be deportees, now being held in detention centers in Florida, are talking about what happened during the ordeal. Mohamed, who came to the U.S. in 2002 as a teenager and was given pending deportation orders in 2005 after missing a court date, said fights broke out on board as passengers tried to use the bathroom.
