The protesters wanted to hold a demonstration on the southern outskirts of the capital Rabat in front of what they said was a secret government detention center.
However, anti-riot police dispersed the crowd before their rally could even begin. Another demonstration has been planned in Morocco's commercial capital, Casablanca. The protests are part of an anti-government movement which started in the African nation on February 20.
Human rights and civil groups as well as independent journalists have also joined the movement. They are demanding constitutional reforms that would reduce King Mohammed's powers and make the justice system more independent.
The king has already announced some reforms in an effort to silence protesters. But protesters say that the ruling monarchy must make serious changes to the way it is running the country. The protesters want an end to corruption, torture, and unemployment. The Monarchy is desperate to avoid an Egyptian- or Tunisian-style revolution.
