S.Korean president to convene emergency security meeting after DPRK nuke test

South Korean President Park Geun-hye will convene an emergency security meeting on Wednesday after the Democratic People's Republic of Korea (DPRK)'s surprising announcement of a successful hydrogen bomb test.

The National Security Council (NSC) meeting will be presided over by President Park at 1:30 p.m. local time (0430 GMT), Park's spokesman said in a briefing.

Park is expected to discuss how to deal with the DPRK's fourth nuclear test, a surprise test of a hydrogen nuclear device.

South Korea's vice foreign minister said after an emergency meeting with diplomats that the fourth nuclear test was in violation of the resolutions of UN Security Council that bans the DPRK from conducting any nuclear test.

The vice minister said that the hydrogen bomb test is a serious challenge to world peace.

The South Korean military reportedly strengthened its defense readiness after the nuclear test, saying that it was closely cooperating with the U.S. forces over the raised tensions on the Korean peninsula.
