A right-wing protester screams with anger as riot police shuffle him into a bus Friday while hundreds of war veterans, some scrawling anti-communist slogans with their own blood, demonstrate against a dissident cleric who visited North Korea for reunification talks. About 2,000 radical students supporting the Rev. Moon Ik-hwan battled riot police with firebombs and rocks in Seoul for a second day. Police said there were some injuries and arrests but had no figures. About 10,000 veterans and supporters staged a mostly peaceful march to the presidential mansion to call for the punishment of Moon, who was arrested Thursday after returning from communist North Korea. The protesters demanded dissident groups be disbanded and their members jailed. Many of the protesters were veterans of the Korean War that ended in 1953, but some were veterans from the Vietnam War also took part.
