South Korea strongly condemned North Korea's latest nuclear test Sunday, vowing to push for fresh and the most powerful sanctions by the U.N. Security Council to completely isolate the communist state.
"President Moon Jae-in said the country will never allow North Korea to continue advancing its nuclear and missile technologies," Moon's key security adviser Chung Eui-yong said at a press briefing on the outcome of the National Security Council (NSC) meeting held earlier in the day.
The South Korean president convened an emergency NSC meeting after what appeared to be an artificial quake was detected at the site of the North's previous nuclear tests.
Pyongyang later claimed success in its sixth nuclear test. (Yonhap)
