The South Korean military has fired warning shots after its belligerent neighbour launched an unidentified projectile on Tuesday, 23 May.
The repeated tests of weapons of mass destruction by Pyongyang have caused Washington to toughen its rhetoric since the inauguration of President Donald Trump, whose administration has suggested the possibility of staging a preemptive attack on North Korea, substantially increasing tensions on the Korean Peninsula.
The missile advances North Korea's weapons capabilities because solid-fuel missiles can be fired faster and more secretly than those using liquid fuel, which much be added separately and transported to a launch site using trucks that can be seen by satellites. The news agency also reported the object as a drone.
On Sunday Pyongyang conducted what it said was a successful test of a medium-range ballistic missile.
Kim reportedly said the launch was a success, "approved the deployment of this weapon system for action" and said that it should "be rapidly mass-produced".

The United States has been trying to persuade China, North Korea's lone major ally, to do more to rein in North Korea, which has conducted dozens of missile launches and tested two nuclear bombs since the start of previous year, in defiance of U.N. Security Council sanctions and resolutions.
Ahead of its emergency meeting, the Security Council has vowed to redouble its efforts to introduce a raft of tough sanctions on the North. Local media said it may have been a North Korean military drone.
North Korea conducted two nuclear tests a year ago. But he said the USA was in the early stages of applying economic and diplomatic pressure, and that perhaps North Korea was "acting out now in response to some of this pressure that I believe they're beginning to feel".
The launch came just one week after the North fired a Hwasong-12 intermediate-range missile, which according to Pyongyang flew nearly 800 kilometres and was capable of carrying a "heavy" nuclear warhead.
If so, it wouldn't be the first time Seoul has reported a drone crossing over the border from the North.
North Korea on May 22 declared its medium-range Pukguksong-2 missile ready for deployment after a weekend test, the latest step in its quest to defy United Nations sanctions and develop a weapon capable of striking USA targets.
