North Korea is believed to have conducted a fifth nuclear test, its most powerful to date, South Korea's military said Friday after monitors detected a 5.3-magnitude "artificial earthquake" near its main nuclear site.

The North's third nuclear test, staged in February 2013, was previously considered the most powerful to date, with a yield of six to nine kilotons.
Authorities in Japan and South Korea said the tremor, measured at 5.3 by the US Geological Survey, showed every sign of another test, the latest since a January 6 test at Punggye-ri.
"The 10-kiloton blast was nearly twice the fourth nuclear test and slightly less than the Hiroshima bombing, which was measured about 15 kilotons," said Kim Nam-Wook from the South's meteorological agency said.
