North korean missile launch
North Korea has fired what is believed to be its first intercontinental ballistic missile in more than four years as Western leaders gather in Brussels for a security summit.
North Korea has tried a prohibited intercontinental long range rocket (ICBM) interestingly beginning around 2017, South Korea and Japan say.
ICBMs, designed for nuclear arms delivery, could extend North Korea's strike range as far as the US mainland.
The test is being viewed as a significant heightening by the North and has been denounced by its neighbors and the US.
Kim Dong-yub, a professor at the University of North Korean Studies in Seoul, said data indicates Thursday's missile could have a maximum range of about 15,000 kilometers.
South Korea's military responded with five missile tests of its own, from land, sea and air.
