China air force video appears to show simulated attack on island resembling Guam

China's air force has released a video showing a simulated attack by nuclear bombers on an island that appears to resemble the US Pacific base on Guam amid rising tensions.

The video, released on the People's Liberation Army Air Force Weibo account, came as Chinese military exercises near Taiwan continued as a senior US official visited the island.

The Pacific island of Guam is home to key US military facilities and would prove vital in any regional conflict.

Titled 'The god of war H-6K goes on the attack', the video showed H-6 bombers, which are capable of carrying nuclear weapons, taking off from a desert base.

Halfway through, a Chinese pilot hits a button and releases a missile at an unnamed coastal runway.

The weapon streaks towards a runway that commentators believe resembles the US Air Force's Andersen base on Guam.

Shots from the footage appear to have been lifted from Hollywood action movies. Explosive missile scenes resemble those seen in Transformers and The Hurt Locker.

The video closes with images of the ground shaking followed by aerial views of a giant explosion.

"We are the defenders of the motherland's aerial security; we have the confidence and ability to always defend the security of the motherland's skies," the Chinese air force wrote in a brief description for the video.

The H-6 bomber has flown during multiple Chinese training missions around and near Taiwan, according to Taiwan's air force, including those last week.
