North Korea said Tuesday foreigners should leave South Korea or make preparations to take shelter, warning that the Korean Peninsula "is inching close to a thermonuclear war."

The warning, issued in the name of the Korea Asia-Pacific Peace Committee, is the latest threat of war Pyongyang has unleashed against South Korea and the United States in recent days.

"The committee informs all foreign institutions and enterprises and foreigners including tourists in Seoul and all other parts of South Korea that they are requested to take measures for shelter and evacuation in advance for their safety," the committee said in a statement carried by the official Korean Central News Agency.
