Algiers, Algeria (CNN) -- Tensions erupted in another restive North African nation as security forces in Algeria on Saturday clashed with anti-government protesters chanting "change the power".
Police detained about 100 protesters in the nation's capital of Algiers, according to the Algerian League for Human Rights. The league is one of the main opposition groups that organized the rallies -- unauthorized gatherings that came a day after embattled Egyptian President Hosni Mubarak stepped down.
The demonstrations were mostly peaceful, with police rounding up protesters in small groups to break up the crowds, and anti-riot police gathered at the scene.
Khalil AbdulMouminm, the general secretary for the Algerian league, called the situation "very tense on the ground" and said police were preventing protesters from assembling, with authorities blocking all entrances to the capital. CNN
