UN Finds Evidence of February 12 Nuclear Test by North Korea

Which the North Korean regime touted

A U.N. agency tasked with looking for signs of nuclear explosions says its monitoring stations have detected radioactive gases that could be linked to North Korea's Feb. 12 test.

CTBTO says stations in Japan and Russia have picked up "significant" traces of noble gases that accompany a nuclear explosion and say they "could be attributed" to the North's test.
