North Korea is preparing to launch a missile on Nov. 8, the day of the U.S. presidential election.
The U.S. military and South Korean forces have issued a high alert to troops in the Korean peninsula in anticipation of the election day missile test.
Officials expressed concern North Korea will launch the BM-35, or Musudan rocket -- missiles capable of reaching the U.S. Pacific territory of Guam located 1,800 miles away, the Yonhap News Agency reports.
The western Pacific territory of Guam has multiple American strategic military assets arranged to check the perceived threat of North Korea.
According to the Daily Star, a military source said: "Speculation of a launch taking place in the near future comes as North Korean experts have said Pyongyang will likely want to send a strong message to the next president."
U.S. Republican presidential nominee Donald Trump openly threatened to nuke North Korea unless it got off its current path of provocative military policy.
North Korea's Musudan missiles are mounted on mobile launches and are located north of the border with South Korea; their movement is being observed by the U.S. ally.
South Korea has detected a Musudan missile near Kusong in the North Pyongan province, the area from which Kim's secretive regime has launched a Musudan missile in October.
North Korea test launched the Musudan rocket for the first time on April 15, despite first fielding a Musudan rocket in 2007.
Since the first launch, the rogue state has fired eight missiles, of which only one flew a significant distance. Reaching an altitude of 900 miles, the June 22 missile flew only about 250 miles.
The North continues to conduct nuclear and missile tests despite sanctions by the international community.
A Seoul Joint Chiefs of Staff official said they are "closely watching every move by the North Korean military at its Punggye-ri nuclear test site and other possible missile-launching sites."
"The military is fully prepared to respond to any provocative acts by the North," the official added.
According to the Daily Mail, a military representative added: "All military and security matters, including the deployment of an advanced missile defence system known as Thaad, will be pushed forward as planned."
