South Korea staged a massive military exercise off its west coast today in defiance of warnings from the North that such drills could trigger war. Ten warships fired artillery and dropped anti-submarine bombs in waters near where South Korea's Cheonan warship was sank by what an investigation concluded was a North Korean torpedo, the AP reports. It was the first such drill since the March sinking killed 46 sailors.
South Korea plans two major joint military drills with US forces this summer. "We call on North Korea to cease all acts of provocation and to live up with the terms of past agreements, including the armistice agreement," America's top commander in South Korea told a Memorial Day gathering today. The North, meanwhile, which denies sinking the Cheonan, said it was scrapping a naval agreement aimed at preventing accidental military clashes and warned that "immediate physical strikes will be launched" on any South Korea warships that intrude into its western waters.
