China's air force has released a video showing nuclear-capable H-6 bombers carrying out a simulated attack on what appears to be Andersen Air Force Base on the U.S. Pacific island of Guam, as regional tensions continue to rise.

The video, released Saturday on the People's Liberation Army Air Force Weibo account, came as China carried out a second day of drills near Chinese-claimed Taiwan, to express Beijing's anger at the visit of a senior U.S. State Department official to Taipei.

Guam is home to major U.S. military facilities, including the air base, which would be key to responding to any conflict in the Asia-Pacific region.
