The US has conducted a joint military exercise with South Korea, flying two strategic bombers over the Korean peninsula.
Two bombers operating out of Andersen Air Force Base in Guam carried out the drills, US Pacific Air Forces said in a statement.
It said the US warplanes flew with F-15K from the South Korean air force and fighters from Japan Self-Defense Force in the first nighttime B-1 bomber exercise between the three allies.
The warplanes first conducted a simulated air-to-ground missile drill over the waters east of the Korean Peninsula and then flew over South Korea and conducted the same drill over the waters west of the peninsula, the South Korean military said.
It comes amid heightened tensions with North Korea over its nuclear programme.
