Roman Catholics and protesters hold a candlelight vigil during a special service as part of protests against the South Korean government's policy toward US beef imports in front of the Seoul City Hall in Seoul on June 30, 2008. South Korean police on June 30 took a harder line against protests over US beef imports which have disrupted the capital for weeks, raiding the offices of civic groups and detaining 148 people. The country's top prosecutor said the candlelit protests, originally sparked by fears of cow disease, have been hijacked by violent radicals. AFP PHOTO/KIM JAE-HWAN
