A United States Air Force B-52 bomber

A US long-range heavy bomber flew over South Korea on Sunday, the US military said, days after North Korea conducted its first alleged hydrogen bomb test in defiance of international sanctions.

The B-52 Stratofortress, which is capable of carrying nuclear weapons, briefly roared over the Osan Air Base, some 72 kilometres (45 miles) south of the inter-Korean border, the military and an eyewitness said.
