IMZOUREN - Moroccan police have detained four people in northern Morocco, an official and an activist said, as protests continued for a second week in the neglected Rif region.
"There have been three arrests in the past 24 hours," an official source said, without identifying those detained.
A local activist said six people had been brought in for questioning - "three in the city of Al-Hoceima and three in nearby areas".
A leading protest figure was detained on Saturday afternoon near his home in Al-Hoceima, a source close to the protesters and the official source said.
