Thousands of people in several Moroccan cities on Sunday took part in peaceful demonstrations calling for reform and social justice, dpa reported.
The demonstrations were called by Islamist and leftist groups that staged similar protests in February and March.
State media reported that some 4,500 people took part in a demonstration in the financial capital Casablanca and around 2,500 in the capital Rabat.
Witnesses however, put the number of demonstrators in Casablanca at around 10,000.
Morocco has been largely unaffected by the unrest in other parts of the Arab world. King Mohammed VI has announced constitutional reform, which would limit the powers of the king.
