Thousands of Moroccans gathered in Marrakesh over the weekend at the site of a bomb attack on the Cafe Argana that killed 17 people on April 28.
Flowers were laid in memory of the victims, who included 8 French people.
The authorities say the suspected bomber disguised himself as a hippy to plant the two bombs.
One protester said:
“The demonstration by these people against terrorism, with candles and flowers, gives a new life to the city of Marrakesh, especially the square of Jmaa al-Fnaa”
Al Qaeda in the Islamic Maghreb denies involvement in the bombing, although the police say at least one of the 3 people arrested for the attack is loyal to the organisation.
The group has claimed responsibility for incidents in the past, particularly in Algeria.
