Algiers - Weeks of heightened tensions between rival communities in the flashpoint oasis town of Ghardaia in southern Algeria have erupted into violence, leaving one person dead and several injured, officials said on Monday.
Schools and shops were shut after a group of youths went on the rampage on Sunday, attacking five different neighbourhoods and after a 39-year-old man was stabbed in the chest at his home.
Another 10 people were wounded in the desert town 600km south of Algiers, among them three policemen, interior Minister Tayeb Belaiz said, cited by official Algerian media.
"The clashes continued until 07:00 (06:00 GMT) this morning. The police managed to restore calm," Ahmed Baba Aissa, spokesman for the Ghardaia co-ordination committee, told AFP.
His association was created a month ago to try and defuse ongoing tensions between the Chaamba community of Arab origin and the Mozabites, a Berber minority group which adheres to the Ibadi faith, an offshoot of Shi'ite Islam.
"Until Sunday, a group of youths was spreading fear by attacking different neighbourhoods, one after the other. Then yesterday [Sunday], five neighbourhoods were attacked simultaneously," Baba Aissa said.
One Mozabite, Belhadj Kebaili, 29, was stabbed to death in his home and numerous others were wounded, he added.
Hamou Mesbah, a senior member of the opposition Socialist Forces Front in Ghardaia, insisted the Chaambas and Mozabites had co-existed peacefully for centuries and accused "a gang of criminals" of being behind the latest violence, with the complicity of some local police.
"Some want to create trouble in Ghardaia ahead of April's presidential elections," he said.
"The problem is that Ghardaia is fertile ground for stirring unrest. It's a transit town for drug trafficking," he added
In recent years, there have been numerous outbreaks of sectarian violence in the town that lies deep in the Sahara desert.
Resentment runs high in the region over the lack of opportunity despite its vast energy riches, with stability further undermined by illegal drug trafficking and the threat from Islamist militants.
