North Korea has fired an Intercontinental Ballistic Missile (ICBM) designed to hit targets on the other side of the world.
The ICBM launch is Pyongyang's seventh this year, and comes amid concerns that it will soon test a nuclear weapon, said South Korea.
According to BBC report, the fire comes a day after both Koreas fired missiles in an escalation of tensions.
North Korea's multiple launches comes as the US and South Korea are staging their largest-ever joint air drills, which Pyongyang has strongly criticised as "aggressive and provocative".
On Thursday North Korea fired a long-range missile at around 07:40 local time, according to a statement from South Korea's Joint Chiefs of Staff.
It flew for about 760km and reached a height of around 1,920 km.
But it appeared to have failed mid-flight, according to Yonhap news agency citing sources.
