North Korea to launch live-fire drills near disputed sea border with South

North Korea conducted similar drills last year, with more than 100 rounds landing south of border, prompting the South to fire hundreds of rounds back.

The South's joint chief of staff said in a statement that North Korea told Seoul that it would carry out the drills from May 13-15 north of the Northern Limit Line, the west coast maritime border.

"If North Korea makes any provocation in our waters, we will strongly respond to it," the statement said.

North Korea's military threatened last week to launch "targeted strikes" against South Korea's navy, accusing the South of violating territorial waters.

North Korea, heavily sanctioned by the United Nations for its missile and nuclear tests, is technically still at war with the South after the 1950-53 conflict ended in a truce, not a peace treaty. (Reporting by Ju-min Park; Editing by Nick Macfie)
