Tight security for President Bush's South Korean visit
Updated
US President George Bush has had a mixed reception to the start of his two-day visit to South Korea.
Around 30,000 people gathered on Tuesday for a Christian prayer service in support of his visit, but later in the day several thousand anti-Bush protestors held a demonstration in central Seoul.
Police used water cannon to dispel the demonstrators.
Mr Bush is due to meet President Lee Myung-bak later today, for talks expected to focus on trade, and on ending North Korea's nuclear program.
