China's military and defense ministry on Sunday confirmed that military forces in a border region near North Korea conducted live-fire drills amid tensions between North Korea and the United States.

The Pentagon, meanwhile, canceled a planned test launch of a Minuteman III ballistic missile to avoid further upsetting ties with North Korea.

Intelligence sources said signs continue to indicate that North Korea is planning to conduct a flight test soon of its intermediate-range Musudan missile that has enough range to reach Guam.

Two Musudan missiles have been readied and the flight test may take place around April 15, the anniversary of the birth of the late leader Kim Il Sung, grandfather of current leader Kim Jong Un.

Additionally, North Korea may conduct another underground nuclear test in the coming days, the sources said, based on intelligence indicators of increased activity at North Korea's northern nuclear testing facility.
