A USAF’s B-52 bomber has flown over South Korea, Sunday, in a show of force after North Korea’s widely disputed claim of a hydrogen bomb test.

The B-52 long range bomber which is capable of carrying nuclear weapons, could be seen flying over Osan Air Force Base south of Seoul, and was flanked by two fighter planes, a U.S. F-16 and a South Korean F-15.

“This was a demonstration of the ironclad U.S. commitment to our allies in South Korea, in Japan, and to the defense of the American homeland,” said Adm. Harry B. Harris Jr., commander U.S. Pacific Command, in a statement. “North Korea’s nuclear test is a blatant violation of its international obligations.”

North Korea will likely see it as a threat.

Earlier on Sunday, the state news agency of North Korea quoted Kim as saying no one had the right to criticize its nuclear tests.

“The DPRK’s H-bomb test … is a self-defensive step for reliably defending the peace on the Korean Peninsula and the regional security from the danger of nuclear war caused by the U.S.-led imperialists,” it quoted Kim as saying.

“It is the legitimate right of a sovereign state and a fair action that nobody can criticize,” he said.

The North’s official name is the Democratic People’s Republic of Korea.
