SEOUL, South Korea — Presidential candidates traded charges of corruption and cruelty Saturday as thousands of riot police stood guard to prevent attacks and violence by rival supporters.
Ruling party candidate Roh Tae Woo, visiting the central city of Taejon, attracted the largest crowd yet in his campaign. Korean news media estimated that about 400,000 people turned out to cheer him.
Meanwhile, South Korea's Defense Ministry announced that North Korean troops opened fire across the demilitarized zone Saturday, wounding a South Korean soldier. The South Korean side returned the fire, it said.
Roh and the top two opposition candidates--Kim Young Sam and Kim Dae Jung--held rallies in different parts of the nation as they stepped up their campaigns for the Dec. 16 elections.
