North Korea on Sunday released propaganda photos of a US bomber and a supercarrier under attack, hours after the same type of aircraft flew in international airspace off the country's eastern coast.

A state-owned propaganda site, DPRK Today, unveiled a doctored photo in which Pyongyang's Pukguksong missile strikes a US strategic bomber B-1B.

DPRK is short for the Democratic People's Republic of Korea, the North's full name.

The photo was released merely hours after the US military announced US Air Force B-1B Lancer bombers, deployed from Andersen Air Force Base in Guam, flew with F-15C air superiority fighters from Kadena Air Base on Okinawa. It was designed as a show of force against North Korea amid an escalating war of words between Pyongyang and Washington.
 

The photo was part of a video that also portrayed US President Donald Trump, seen speaking at the celebration of the US Air Force's 70th Anniversary at Joint Base Andrews, as "a mad man."

Then the North's Pukguksong-2 missile, a medium-range ballistic missile, is seen launched toward a B-1B and a F-35, and the photo captures the two jets engulfed in computer-generated fire.
 

Also in the video, a North Korean submarine-launched missile strikes the USS Carl Vinson, a nuclear-powered flattop.

The subtitle of the film says, "Should F-35, B-1B and the Carl Vinson lead the US attack, they will head to the grave in that order." (Yonhap)
