Three Saudis are to be charged in a special criminal court in Riyadh with incitement to violence and rebellion, said sources at the Commission for Control and Investigation.

A judiciary source said the court will hear the defendants once they are formally arraigned.

The tweets posted on Twitter indicate involvement in such acts, said the source.

The source said that the three defendants will be put on a preliminary list of terrorists who are charged by the Ministry of Interior with participation in or incitement to fighting in conflict zones abroad through issuing Islamic edicts or showing support toward such groups. The list also includes those who disseminate inflammatory material in media outlets, donate money to terrorists or adopt their logos or slogans.
