TOKYO (Sputnik) — Earlier in the day, Pyongyang claimed it had carried out the first test of a hydrogen bomb. Several states, especially neighboring South Korea and Japan, have subsequently called for new sanctions against the country.
"It is hard to regard this test as that of a hydrogen bomb," the military official said, as quoted by Yonhap.
South Korean intelligence said earlier on Wednesday the hydrogen blast in North Korea was unlikely hydrogen-based, assuming that a magnitude of an earthquake caused by the nuclear test was not high enough.
