South Korea and U.S. on missile watch as North hails Kim dynasty

SEOUL (Reuters) - South Korea and the United States were on high alert for a North Korean missile test-launch on Thursday, as the isolated state celebrated the rule of the Kim dynasty and appeared to tone down rhetoric of impending war.

Despite recent threats to attack U.S. bases and the South, North Korea started to welcome a stream of visitors for Monday's celebrations marking the birthday of its founder Kim Il-sung.
