North Korea fired an intercontinental ballistic missile on Friday, capable of hitting Los Angeles and other US cities, according to North Korean officials.
However, Pentagon spokesperson Navy Captain Jeff Davis said the North American Aerospace Defence Command determined the launch did not pose a threat to the US.
Us President Donald Trump condemned the launch and said these tests are not ensuring North Korea’s security.
“By threatening the world, these weapons and tests further isolate North Korea, weaken its economy, and deprive its people,” he said.
The US Eight Army and South Korean army personnel have since conducted a combined training event to exercise their assets against North Korea, which include the Army Tactical Missile System.
The Pentagon said this system can be deployed at any time to ensure the US-South Korea alliance can engage all the critical targets under any weather conditions.
Mr Davis said the US is committed to do whatever it takes to keep its allies safe.
“The United States’ commitment to the defence of its allies, including South Korea and Japan, in the face of these threats, remains ironclad,” he said.
“The United States also remain prepared to defend itself and its allies from any attack or provocation.”
According to the Pentagon, the missile was launched in Mupyong-ni and travelled 1000 kilometres, before landing in the waters off the Japanese coast.
The US Defence Department is working with its interagency partners on a more detailed assessment.
North Korea successfully launched its first intercontinental ballistic missile on July 4, and this was their second test this month.
