Rwandan opposition activist Diana Rwigara has spoken to the BBC’s Newsday programme about why she wrote an open letter to her president about the death of a prison guard.
Ms Rwigara published the letter to President Paul Kagame last week about the murder of Paul Mwiseneza.
In the letter, she said he was killed shortly after talking to her about unrest at a prison in the capital, Kigali.
She told Newsday that this was yet another example that the government did not tolerate a dissenting voice.
“We live in a country where daring to voice your opinion, daring to criticise the government will get you killed,” she said.
