S. Korea, U.S. deploy B-52 strategic bomber over Korean Peninsula

South Korea and the United States said Sunday they had deployed the B-52 Stratofortress, a long-range strategic bomber, over the Korean Peninsula, three days after North Korea said it had tested a hydrogen bomb, according to South Korea's largest news agency Yonhap.

It is reported the B-52 bomber left U.S. Andersen Air Force Base in Guam on Sunday morning and arrived in the skies above Osan, Gyeonggi Province, at noon, according to Yonhap News Agency.

This was a demonstration of U.S. "ironclad commitment to our allies in South Korea, in Japan, and to the defense of the American homeland," Admiral Harry B Harris Jr, commander of the U.S. Pacific Command, wrote on Twitter.

The bomber flew past Osan surrounded by an entourage of two South Korean F-15Ks and two U.S. F-16s, the two sides' militaries said.

The deployment is the second countermeasure employed by the South since North Korea announced its H-bomb test Wednesday.
