North Korean leader Kim Jong Un again supervised the test-firing of a "newly developed" weapon, state media reported Sunday -- further muddying the waters for any resumption of denuclearisation talks.
South Korea's military had said the North launched what appeared to be two short-range ballistic missiles on Saturday, but the North's state media said a "super-large multiple rocket launcher" had been tested.
It was the latest in a series of launches the nuclear-armed North has conducted in recent weeks in protest at US-South Korean joint military exercises, which wrapped up nearly a week ago.
Kim said the "newly developed" system was a "great weapon," and expressed "high appreciation" for the scientists who had designed and built it, the country's official Korean Central News Agency said.
"The test-fire proved that all the tactical and technological specifications of the system correctly reached the preset indexes," the report said.
Kim also said the country needed to keep stepping up weapons development "for resolutely frustrating the ever-mounting military threats and pressure offensive of the hostile forces," KCNA noted.
Kim has reportedly observed at least two other tests of "new" weapons this month alone, though the nature and technical specifications of those weapons remain a mystery.
Saturday's test prompted South Korea's presidential Blue House to convene a National Security Council meeting.
"NSC members agreed to continue diplomatic efforts with the international community to bring the North back to the negotiation table with the US to achieve the goal of complete denuclearisation in the Korean peninsula," the government said in a statement.
But launching those talks anytime soon looks to be a fading possibility.
On Friday, North Korea lashed out at US Secretary of State Mike Pompeo, calling him a "diehard toxin" and saying it was "sceptical" whether it can negotiate with him.
Pyongyang also vowed to remain the United States's "biggest 'threat'" and said the annual US-South Korea joint military drills had "complicated" nuclear talks between the two countries.
"We are ready for both dialogue and stand-off," North Korea's foreign minister Ri Yong Ho said in a statement.
