US Air Force B-1 bombers, accompanied by fighter jets from South Korea and Japan, conducted a flyover near the Korean peninsula on Thursday, according to a statement from the US Air Force -- a move that has drawn harsh criticism from North Korea ahead of President Donald Trump's trip to the region.

Two B-1B Lancers from Anderson Air Force Base in Guam rendezvoused with the Japanese and South Korean jets as part of the planned "bilateral integration" exercise -- at one point flying over South Korea.
