US, SKorea launch war games in tense Yellow Sea

A US super-carrier and South Korean destroyer took up position in the tense Yellow Sea on Sunday for joint military exercises that were a united show of force just days after a deadly North Korean artillery attack.

As tensions escalated across the region, with North Korea threatening another "merciless" attack, China belatedly jumped into the fray. Beijing's top nuclear envoy, Wu Dawei, called for an emergency meeting in early December among regional powers involved in nuclear disarmament talks, including North Korea. (AP)
