TOKYO (Reuters) - Prime Minister Shinzo Abe said on Friday that a suspected nuclear test by North Korea could not be tolerated and that Japan would protest strongly to Pyongyang if confirmed. A seismic tremor was recorded in an area around North Korea's known nuclear site on Friday, and was suspected to be the fifth nuclear test by the isolated nation.
