Bahraini human rights activist Nabeel Rajab has been granted a royal pardon for health reason after spending two months in jail over a tweet that alleged some of the Gulf Kingdom's soldiers had defected to the Islamic State (Isis).

King Hamad made the order for fears over Rajab's health. Upon his release, Rajab tweeted:
