North Korea launches a new intercontinental ballistic missile designed to threaten U.S.

North Korea launched a new intercontinental ballistic missile Thursday in its first test in almost a year of a weapon designed to threaten the U.S. mainland and occurring days ahead of the U.S. election.

North Korean leader Kim Jong Un ordered the missile test and was at the launch site, calling the launch "an appropriate military action" to show North Korea's resolve to respond to its enemies' moves that has threatened the North's safety, according to its Defense Ministry.

The United States, South Korea and Japan had also identified the weapon as an ICBM and condemned the launch as raising tensions. The launch came as Washington warned that North Korean troops in Russian uniforms are heading toward Ukraine, likely to augment Russian forces and join the war.

North Korea confirmed the launch hours after its neighbors detected the firing of what they suspected was a new, more agile weapon targeting the mainland U.S. The statement was unusually quick since North Korea usually describes its weapons tests a day after they occur.

"I affirm that the DPRK will never change its line of bolstering up its nuclear forces," Kim said, according to a North Korean Defense Ministry statement carried by state media. DPRK stands for the Democratic People's Republic of Korea, North Korea's official name.

South Korea's Joint Chiefs of Staff said North Korea could have tested a new, solid-fueled long-range ballistic missile. Missiles with built-in solid propellants are easier to move and hide and can be launched quicker than liquid-propellant weapons.

JCS spokesperson Lee Sung Joon said the launch was possibly timed to the U.S. election in an attempt to strengthen North Korea's future bargaining power. He said the North Korean missile was launched
