The prominent Bahraini human rights activist Nabeel Rajab has been sentenced to six months in prison over a tweet in which he suggested Bahraini jails served as an "ideological incubator" for jihadists.
The founder of the Bahrain Centre for Human Rights has been imprisoned several times for his activism.
Speaking to the BBC after his sentencing, Mr Rajab said the sentence was designed to prevent him from speaking up and also accused the British government of silence on his case.
Amnesty International said the sentence was "a blow to freedom of expression".
