S. Korea, US begin annual drills amid N. Korean threats

SEOUL, South Korea — South Korean and US troops began annual military drills Monday that rival North Korea warned could trigger a nuclear war on the divided peninsula.
Despite North Korean threats to retaliate, South Korea and the United States went ahead with the drills, which are the allies' first major combined military exercises since the North shelled a front-line South Korean island in November, killing four people.
