>SEOUL, South Korea (AP) – A North Korean defector tried to set himself on fire to halt the Olympic torch relay through Seoul, while thousands of police guarded the flame Sunday from protesters blasting China’s treatment of North Korean refugees. Hundreds of China supporters waving the Chinese flag greeted the torch, throwing rocks at anti-Beijing demonstrators. Police ran alongside the flame and rode horses and bicycles on the relay across the city, which hosted the 1988 Olympics.
