Algerian soldiers fired on demonstrators Monday, killing at least 12 people, witnesses said. An Islamic group said more than 250 people have died in weeklonganti-government protests. The gunfire occured in Bab-el-Oued, a district in western Algiers, as 10,000 people responded to a call by the Islamic fundamentalistsfor a "peaceful march of protest." It was the latest clash in a week of bloody riots against spiraling prices and the economic policies of President Chadli Bendjedid's government. No official death toll has been issued in the riots, the worst in this North African nation since its independence from France in 1962.
