S. Korea vows retaliation if North attacks again
South Korea's president vowed a relentless retaliation against North Korea if provoked again, saying Monday he is not afraid of a war with the communist North.
The two Koreas have ramped up their rhetoric since North Korea shelled front-line Yeonpyeong Island near the tense western sea border last month, killing four South Koreans. Both sides accuse each other of provoking first. (AP)
