"MAIDUGURI, Nigeria – Nigerian Muslims protesting caricatures of the Prophet Muhammad attacked Christians and burned churches on Saturday, killing at least 15 people in the deadliest confrontation yet in the whirlwind of Muslim anger over the drawings.
It was the first major protest to erupt over the issue in Africa's most populous nation. An Associated Press reporter saw mobs of Muslim protesters swarm through the city center with machetes, sticks and iron rods. One group threw a tire around a man, poured gas on him and set him ablaze."
