The US has flown two supersonic B-1 Lancer strategic bombers over South Korea in a show of force, just days after North Korea carried out its fifth nuclear test.
The two bombers conducted a low-altitude flight over an air base located some 77km (48 miles) from the border.
Pyongyang’s latest nuclear test is believed to be its largest ever.
The US has warned the North of “serious consequences” in light of the test.
B-1 bombers are capable of carrying nuclear missiles and bombs that are able to destroy even underground bunkers.
The fly-over was originally scheduled for Monday but was delayed because of weather conditions in Guam, where the bombers were stationed.
