South Korean and US troops began annual military drills today which North Korea warned could trigger a nuclear war on the divided peninsula.

South Korea’s president said his nation will no longer tolerate North Korea’s “brutality” and said the regime would pay for a surprise torpedo attack that killed 46 South Korean sailors.

South Korea's President Lee Myung-bak will meet a delegation of visiting North Korean officials tomorrow, the latest sign that ties between the divided countries are warming.
