Paul Rusesabagina, who was the subject of Oscar-nominated film Hotel Rwanda, has had a stroke in prison in Rwanda where he is serving time for terrorism, his daughter has told the BBC.
He was sentenced to 25 years last year in what supporters called a sham trial.
The are now trying to sue Rwanda over his alleged abduction and torture.
“Right now my father is sick. He is being deprived of the proper medical treatment and he actually had a stroke in prison,” Carina Kanimba told BBC Focus on Africa radio.
“Now he has partial facial paralysis,” she added.
Rwanda denies that Rusesabagina was kidnapped and has said he received a fair trial.
