North Korea: Pyongyang confirms success of fifth and largest nuclear test

North Korea announced its fifth successful nuclear test, Friday morning, stating that it is now able to mount nuclear warheads on ballistic rockets. The announcement came after a large seismic event was identified at the country's nuclear test site.
The US Geological Survey (USGS) detected a powerful explosion at the test site, reportedly measuring 5.3 in magnitude, igniting reports of the nuclear test, believed to be the country's most powerful yet.
A statement from Pyongyang on the use of nuclear warheads on ballistic rockets, posted by the Korean Central News Agency, reads; "The standardisation of the nuclear warhead will enable the DPRK [North Korea] to produce at will and as many as it wants a variety of smaller, lighter and diversified nuclear warheads of higher strike power."
South Korea's Defense Ministry has since confirmed the launch, with Prime Minister Hwang Kyo-ahn expected to gather the country's National Security Council (NSC) for an emergency meeting. After mounting an official protest against the launch, Japan is also set to hold a high level meeting of senior officials on the test, led by Prime Minister Shinzo Abe.
