"N. Korea fires about 100 rounds of artillery into Yellow Sea"

"SEOUL, Aug. 9 (Yonhap) -- North Korea on Monday fired some 100 rounds of artillery into its side of a disputed border with South Korea in the Yellow Sea, a South Korean military source said.

The North Korean move comes right after South Korea ended large-scale five-day navy exercises near the inter-Korean border in a show of force against its communist neighbor blamed on sinking one of its warships in March.

North Korea had warned of "strong physical retaliation" against the drills that it denounced as preparations for a northward invasion."
