North Korea To Suspend Naval Hot Line With South

North Korea said on Thursday that it was cutting off a naval hot line used to prevent clashes on its disputed sea border with South Korea, while the South conducted a large naval drill in a show of force after the sinking of one of its warships. Cutting the phone line, installed after deadly skirmishes in 1999 and 2002, raises the chances of an armed clash in tense western waters — something the North has said could happen any time.The two sides have disagreed on the line for a western sea border since the Korean War ended with a truce in 1953. On Thursday, North Korea’s military said it would “completely nullify” a 2004 accord aimed at preventing accidental armed skirmishes along the disputed sea border, scene of three bloody maritime battles in the past decade. The agreement called for both navies to communicate through a common radio frequency and maintain a phone line to handle emergencies.
