French minister sends riot police to Marseille

France's interior minister sent extra riot police to the southern port city of Marseille on Sunday after a group of marauding teenagers torched a bus, seriously burning a young passenger. French police have braced for a surge of violence this weekend, as Friday was the first anniversary of the start of riots in poor neighborhoods where many immigrants and their French-born children live. There was scattered unrest late Friday, but the most serious violence occurred Saturday with the bus attack in Marseille.
