Algeria has adopted legislation to try to retake control of the thousands of extremist mosques in the country, forbidding their use for illicit personal or collective goals or to “harm people or groups.” Last week Algeria offered new gas and oil concessions in the southwest and the north to international bidders, but foreign investment may be hampered by the government’s refusal to allow companies to provide their own armed security, despite terrorists attacks like the In Amenas siege a year ago.
