Who are the US citizens still being detained abroad?

New York native Ryan Corbett was arrested after returning to Afghanistan in August 2022 after having left the country when the Taliban swept to power the previous year.

He had previously lived in the country for many years, and ran and supervised projects for a number of NGOs.

To date, Mr Corbett has not been charged with a crime. Taliban officials have told CBS that he was involved in “anti-state” activities.

He is among three US citizens the US government believes are being held by the Taliban, who have expressed an interest in freeing them in exchange for Afghan citizens still held by the US.

In March, his family said they received a “disturbing call” from Mr Corbett in Afghanistan in which he “exhibited a significantly deteriorated mental state”.

“I want the president to realise that the lack of action to bring Ryan home could have disastrous consequences,” his wife Anna told CBS.

While US officials have held several meetings with Taliban representatives to secure his release, they have not disclosed whether any progress has been made.

Several US lawmakers, including New York representative Claudia Tenney, have also publicly called for his release.
