Missile launch in North Korea: Everything we know about copy tests of banned Russian weapons

North Korea fired a suspected ballistic missile seaward off its east coast on Sunday and it appears to be modeled after a banned Russian weapon.

Kim Jong-un's launch marks escalating tensions as UN bans North Korea from ballistic and nuclear weapons testing, ahead of US Vice President Kamala's visit to region Harris.

This is the 19th missile launch this year and appears to coincide with the arrival of the United States carrier battle group USS Ronald Reagan - a fleet of missile carriers and aircraft carriers - ship which arrived in the port city of Busan, southeastern South Korea, on Friday.

The Japanese Coast Guard confirmed it was likely a ballistic missile launch, according to information from the Tokyo Defense Ministry, and the United States said it was now consulting closely with its allies on the next steps after the explosion.

The launch is the latest provocation of Kim Jong-un's authoritarian regime and although the US Indo-Pacific Command has said the launch poses no "immediate threat to US personnel or territory, or to our allies" , he showed the "destabilizing impact" of the North's illegal weapons program.

Here's everything we know about the launch as tensions mount on the Korean Peninsula.

How far did the missile travel?

South Korea's Joint Chiefs of Staff said the missile launched from the inland city of Taechon traveled 370 miles across the country at a maximum altitude of 37 miles before landing in waters off the east coast of North Korea.

Kim Dong-yub, a professor at the University of North Korea Studies in Seoul, told ABC News that the missile in North Korea traveled the same distance from its Taechon launch point as the distance to to the South Korean port of Busan.

Intelligence agencies in South Korea and the United States are analyzing further details, but Japanese Defense Minister Yasukazu Hamada said the ballistic missile may have flown on an irregular trajectory.

Mr. Hamada said it was launched around 6:52 a.m. local time in Japan, or 10:52 p.m. UK time on Saturday.

It fell "near the east coast of North Korea", outside Japan's exclusive economic zone, he added.

What type of missile was it?

Concrete validation of the missile type is underway, but details of the flight announced by the military in Seoul suggest that North Korea could have tested a nuclear-capable short-range weapon modeled on Russia's Iskander missiles .

The Iskander missile launcher was developed in the 1970s to replace the Soviet Union's Scud-B missile system, and the United States opposed its sale, claiming that the cruise missiles used by the 'Iskander-K violates mid-range nuclear. Forces Treaty (INF) due to their immense range.

They travel at relatively low altitudes and are designed to be maneuverable in flight, making them more difficult for missile defenses to intercept.
