Algeria deployed police to mosques and other areas in the capital on Friday, as new riots broke out over rising food prices and high unemployment.
Witnesses say protesters took to the streets in Algiers late Thursday and Friday, tossing stones at police, who responded by firing tear gas.
Government officials also canceled football (soccer) games this weekend.
The unrest began this week after the sudden price hike of food staples such as flour, sugar and oil.
Protesters are also blaming government policies for continuing unemployment and economic problems, despite the country's oil and gas wealth.
In neighboring Tunisia, violent protests over unemployment have led to three deaths in recent weeks.
Some information for this report was provided by AP, AFP and Reuters.
