SEOUL, Sept. 9 (Yonhap) -- Prime Minister Hwang Kyo-ahn is set to hold an emergency National Security Council (NSC) meeting later in the day, the presidential office said Friday, amid rising speculation that Pyongyang conducted its fifth nuclear test.
Jung Youn-kuk, presidential spokesman, said the meeting will be held at Cheong Wa Dae after a magnitude 5 earthquake was detected at North Korea's nuclear site in the country's northeastern region earlier in the day.
Political sources said Hwang has cleared his schedule to attend the meeting.
