Koreas Fire on Each Other at Sea Border

So much for rapprochement. South Korean and North Korean navy patrol boats exchanged fire at a disputed western sea boder Tuesday, just three days after the longtime Asian rivals raised hopes for an improvement in relations by agreeing to resume high-level dialogue this year. No vessel from either side was hit in the exchange from heavy machine guns, according to the South Korean military. The incident began when a North Korean patrol boat breached the disputed sea border and sailed half a nautical mile into waters controlled by South Korea, military officials said.
