Demonstrators blocked roads, sacked public buildings and overturned vehicles in the Bouira region, southeast of the capital, Algiers, the reports said.
In the western Tiaret region and in Sidi Ammar in the east, hundreds of people blocked highways to protest against higher transport prices caused by the increase in fuel costs.
The protest movements began on Saturday and continued into Sunday, causing security forces to intervene, newspapers said. Dozens of people were questioned.
Riots also broke out in the western Maghnia region near the Moroccan border, as demonstrators built and set fire to roadblocks to protest at deteriorating economic conditions.
