Kim says N. Korea has hydrogen bomb
North Korean leader Kim Jong-un appeared on Thursday to claim his country has developed a hydrogen bomb, a step up from the less powerful atomic bomb, but outside experts were sceptical.
Mr. Kim made the comments as he toured the Phyongchon Revolutionary Site, which marks the feats of his father who died in 2011 and his grandfather, state founder and eternal president, Kim Il Sung, the official KCNA news agency said.
The work of Kim Il Sung â€œturned the DPRK into a powerful nuclear weapons state ready to detonate a self-reliant A-bomb and H-bomb to reliably defend its sovereignty and the dignity of the nation,â€ KCNA quoted Kim Jong Un as saying.
DPRK are the initials of the isolated Northâ€™s official nameâ€”the Democratic People’s Republic of Korea. A hydrogen bomb, also known as a thermonuclear bomb, uses more advanced technology to produce a significantly more powerful blast than an atomic bomb.
North Korea conducted underground tests to set off nuclear devices in 2006, 2009 and 2013, for which it has been subject to U.N. Security Council sanctions banning trade and financing activities that aid its weapons programme.
An official at South Koreaâ€™s intelligence agency told Yonhap news agency there was no evidence that the North had hydrogen bomb capacity, and believed Mr. Kim was speaking rhetorically.
