North And South Korea Exchange Artillery Fire In Deadly SkirmishPlay
South Korea's president is vowing to unleash "enormous retaliation" should North Korea attack his nation again. The tough talk came after North Korea fired dozens of rounds of artillery this morning at the disputed Yeonpyeong border island where South Korean forces are based, killing at least two South Korean marines. The south then fired back.
The sharp escalation in skirmishes between the two nations came after the South ignored warnings from the North to stop its military exercises in the area. We speak with BBC correspondent Chris Hogg in Seoul, and Dr. Jim Walsh, international security expert at MIT.
