N. Korean seismic event shows 'explosion-like characteristics'
VIENNA (REUTERS) - A nuclear test monitoring agency said on Tuesday an unusual seismic event detected in North Korea showed "clear explosion-like characteristics" and suggested it occurred at about the same place as previous tests by the North.
Mr Tibor Toth, executive secretary of the Comprehensive Nuclear Test Ban Treaty Organisation (CTBTO), said the seismic event's location was "roughly congruent with" nuclear tests carried out by North Korea in 2006 and 2009.
"For now, further data and analysis are necessary to establish what kind of event this is," he said in a statement.
"If confirmed as a nuclear test, this act would constitute a clear threat to international peace and security, and challenge efforts made to strengthen global nuclear disarmament and non-proliferation, in particular by ending nuclear testing," he added.
