N. Korea Says South Will Pay 'Expensive Price' for Naval Clash

North Korea says South Korea will pay "an expensive price" for firing at a North Korean patrol boat on Tuesday.

The official Rodong Sinmun newspaper published a commentary Thursday saying the clash in the Yellow Sea was not an accident, but instead was a "premeditated act of aggression" by the South. The commentary said the incident was meant to escalate tensions and dampen a positive atmosphere between the two countries.
