Algeria's Salafist groups have opposed plans for building the first Shia mosque in the North African country.
The extremist groups have described the plan as a "threat", according to echoroukonline.fr website.
The protests by radicals came after it was reported that a Shia merchant plans to build a mosque for the followers of Ahl-ul-Bayt (AS) in the city of Tebessa.
Salafist groups have called on Algeria's ministries of interior and Islamic affairs not to issue permission for the construction of the mosque.
They have described activities of Shia groups in Algeria as dangerous and insisted that they will stand against any plans for building mosques for Shias.
Shia Muslims are a minority in Algeria where nearly all the population is Muslim.
