DUBAI - An appeals court in Bahrain upheld a six-month jail sentence against prominent dissident Nabeel Rajab on Thursday for a tweet deemed insulting to the kingdom's security establishment, state news agency BNA said.
He was convicted for "publicly insulting two government bodies," the attorney general's office was quoting as saying, referring to the defense and interior ministries.
Rajab has been a leading figure in protests by the tiny island kingdom's Shi'ite Muslim majority since the 2011 Arab Spring.
He has accused the country's mostly Sunni government of repression and torture. The tweet at the center of his case accused authorities of not tackling the threat of hardline militant groups like Islamic State.
"Many Bahrain men who joined terrorism and ISIS came from security institutions and those were the first ideological incubator," he wrote on Twitter in September.
