N. Korea threatens to retaliate against S. Korea

SEOUL – North Korea's military threatened Wednesday "strong physical retaliation" against planned South Korean naval drills near their disputed sea border and warned civilian ships should stay away from the area.
South Korea plans to hold five-day naval drills in the Yellow Sea, including exercises near the border, beginning Thursday in response to the deadly March sinking of a South Korean warship blamed on North Korea. Forty-six sailors were killed.
