North Korea has a secret, previously unreported missile base near its northern border with China, which could pose a “potential nuclear threat” to much of East Asia and the United States, according to a new report released Wednesday.

Just 27 kilometres away from its border with China, North Korea has a secret missile base in Singpung. This facility, which is larger than New York’s John F Kennedy International Airport, is rumoured to house six to nine of the country’s most advanced intercontinental ballistic missiles.
