The administration of United States President Donald Trump has deported dozens of people to the Central African Republic, including an Afghan whose family members collaborated with the US military, his lawyer and advocacy groups said.

The Afghan man, who is in his early 20s, was granted protection against deportation to Afghanistan by a US judge due to fears of persecution by the Taliban, his lawyer, Alma David, said.

Advocacy organisations AfghanEvac, a US-based group that assists Afghan allies, the American Civil Liberties Union, and Human Rights First also confirmed his deportation.

His family in Afghanistan had received threats from the Taliban, which governs the country, because of his brothers’ involvement in supporting the US military, according to court documents seen by The Associated Press news agency.

One of the Afghan man’s brothers lives in the US and served in the Afghan National Army, which collaborated with the US military before the Taliban seized power in 2021, David said.

Another brother was a pilot trained by the US and later killed by the Taliban, she added.

According to The New York Times, which identified the Afghan man only as Khalil, his sister and father also worked alongside US forces.

The deportation flight landed in the Central African Republic’s capital, Bangui, on Saturday, carrying 12 Afghans and eight Iranians, as well as several people from Nepal and Nicaragua, said Savi Arvey, director of policy, refugee and immigrant rights at Human Rights First.

It was the third deportation flight from the US to the Central African Republic this year, according to the rights organisation.

Under a series of often quietly struck agreements, the Trump administration has sent thousands of people to third countries where they have no ties as it pushes ahead with an immigration crackdown.

The latest US State Department Travel Advisory warns citizens not to travel to the African country for any reason, citing risks of unrest, crime, kidnapping, health, and “terrorism”.
