North Korea has confirmed it conducted its third test-firing of a new "super-large" multiple rocket launcher that it says expands its ability to destroy enemy targets in surprise attacks.
The latest launches extended a months-long streak of weapons displays by the North, which continues to use a standstill in nuclear negotiations to advance its military capabilities while pressuring Washington for concessions.
Pyongyang's official Korean Central News Agency described the tests a day after the South Korean and Japanese militaries said they detected two projectiles launched from an area near the North Korean capital travelling more than 300km cross-country before landing in waters off the North's eastern coast.
Experts say the North could continue to ramp up weapons demonstrations ahead of an end-of-year deadline set by leader Kim Jong-un for the US to offer mutually acceptable terms to salvage a fragile diplomacy strained by disagreements over exchanging sanctions relief and disarmament steps.
Thursday's launches followed statements of displeasure by top North Korean officials over the slow pace of nuclear negotiations with the United States and demands that the administration of President Donald Trump ease crippling sanctions and pressure on their country.
KCNA said Mr Kim expressed satisfaction over what North Korea described as a successful test of its new rocket artillery system, but it wasn't clear whether the leader observed the launches on-site.

The North previously tested the system in August and September.
The latest test verified the "perfection" of the system's continuous firing ability that allegedly allows it to "totally destroy" enemy targets with "superpower", the agency said.
Kim Eun-han, a spokesman of Seoul's Unification Ministry, said South Korea has "strong concern" over the North's weapons activity, but avoided a straightforward answer when asked about the possible impact on inter-Korean dialogue.
Earlier this month, the North test-fired an underwater-launched ballistic missile for the first time in three years.
The North has also tested new short-range ballistic missile and rocket artillery systems in recent months in what experts saw as an effort to use the standstill in talks to advance its military capabilities while increasing its bargaining power.
Negotiations have faltered after the collapse of a February summit between Kim and Trump in Hanoi, Vietnam, where the US rejected North Korean demands for broad sanctions relief in exchange for piecemeal progress toward partially surrendering its nuclear capabilities.
