At least three prominent Saudi clerics, Salman al-Awda, Awad al-Qarni and Ali al-Umari, have been arrested in the last few days. They are not part of the state-backed clerical establishment. Saudi Arabia has always had problems with clerics whose loyalties are not to the royal family, going back to the revolt of the Ikhwan which was ruthlessly suppressed by Ibn Saud in 1929. Nowadays the problem has a new dimension: large online followings. Nearly 60 per cent of the Saudi population are said to be active on social media; al-Awda has more than 14 million followers on Twitter. Le Monde describes him as a defender of individual liberty and one of the most popular challengers of authoritarianism in Saudi Arabia.
