North Korea has vowed to turn Seoul into a “sea of flames” in retaliation to a joint military exercise between the U.S. and South Korea expected to happen today. South Korea says the military exercise is an annual event, but the North says it is a pretext for an invasion and is warning it will respond with “relentless retaliation.” This is a lot like November, when North Korea threatened South Korea with “a merciless shower of fire.” [AP via Gawker]
