Allegations of torture, solitary confinement and suicide attempts by Kylie Moore-Gilbert have quickly been shut down by her family as the Australian-British academic faces her 20th month in prison.

Convicted of espionage in a secret trial, Moore-Gilbert has been sentenced to 10 years in Evin prison.

Both her family and the Department of Foreign Affairs (DFAT) have kept quiet about her case amid speculation of a potential prisoner swap.
