North Korea has carried out another failed missile launch, according to the South Korean military.
The missile is said to be capable of hitting US bases as far away as Guam.
It has been tested eight times this year, with only one success.
However, experts fear it could become operational as early as next year.
The US condemned the launch, calling it a “further provocation”.
North Korea’s last test was denounced by the UN, which has banned it from any use of ballistic or nuclear technology.
