SEOUL/TOKYO -- Northeast Asia is in the grip of an unusually cold snap, with the mercury plummeting in the two Koreas, Japan and China to the lowest levels in around a decade.
South Korea's Meteorological Administration issued a special cold wave warning on Tuesday morning, alerting people to the potential danger of the freeze. Temperatures dropped as low as minus 16 C in Seoul and minus 25 C in Cheorwon County, near the North Korean border.
