The independent website goud.ma meanwhile said one person died during the trouble after being hit by a vehicle. The state news agency MAP said police were hunting "the perpetrators of this crime."
Chabar accused separatists, a reference to the Western Sahara independence movement Polisario Front, of exploiting the disturbances for "political purposes".
The Polisario demands a self-determination referendum in the Western Sahara, a phosphate-rich territory that was annexed by Morocco after Spain withdrew in 1975. Morocco has only offered greater autonomy.
Several witnesses said the clashes erupted Saturday during a show by a popular Moroccan singer. Cars were set ablaze and shops as well as a bank branch were destroyed, according to witnesses reached by telephone.
The week-long Dakhla festival, which kicked off Monday, features several African artists, including South Africa's Johnny Clegg, Ivory Coast's Alpha Blondy and Morocco's Abdelwahab Doukkali.
Saturday almost 1,000 people rallied amid a heavy police presence in Morocco's biggest city Casablanca to demand political reforms and a new constitution, a witness told AFP.
That protest took place nearly a week after thousands of people staged rallies across Morocco demanding political reform and limits on the powers of King Mohammed VI under the so-called "February 20" movement.
Thousands of young Moroccans have joined the "February 20" movement on the social networking site Facebook, calling for peaceful demonstrations demanding a new constitution limiting the king's powers and more social justice.
The call has similar origins to the revolts that toppled decades-old regimes in Tunisia and Egypt and sparked protests in Libya, Bahrain, Yemen, Algeria and Oman.
