S. Korean military: N. Korea's blast doesn't seem to be from H-bomb
SEOUL, Jan. 6 (Yonhap) -- South Korea's military played down North Korea's H-bomb capability Wednesday, saying its new nuclear test doesn't appear to be hydrogen-based, given the intensity of the tremor.
The secretive North announced earlier in the day it has successfully conducted a test of a hydrogen bomb.
"It is hard to regard this test as that of a hydrogen bomb," the military said, requesting anonymity,
"Only a few countries including the U.S. and Russia have conducted hydrogen bomb tests and the size of the detonations reached 20 to 50 megatons," the official said.
The latest North Korean test amounts to 6 kilotons and it's too weak for a hydrogen bomb, he said.
