It is strongly suspected that the 5.3 seismic explosion recorded in North Korea was the country’s 5th nuclear test, not an earthquake, reported the Yonhap News Agency.
Japan Prime Minister Shinzo Abe said on Friday that a nuclear test by North Korea could not be tolerated and that Japan would protest strongly to Pyongyang.
China’s environment ministry has begun emergency radiation monitoring after the suspected nuclear test in North Korea.
The US National Security Council stated:”We are aware of seismic activity on the Korean Peninsula in the vicinity of a known North Korean nuclear test site. We are monitoring and continuing to assess the situation in close coordination with our regional partners.”
