North Korea fired a newly developed anti-aircraft missile on Thursday, state media KCNA reported on Friday, the latest in its recent series of weapons tests amid deadlocked denuclearisation talks with the United States.

Iran PressAsia: The anti-aircraft missile had a "remarkable combat performance" and included twin rudder controls and other new technologies, the official Korean Central News Agency said.

The tests highlighted how North Korea has been steadily developing increasingly sophisticated weapons, raising the stakes for efforts to press it to give up its nuclear and missile programs in return for U.S. sanctions relief.

It was North Korea's second known weapons test this week after launching a previously unseen hypersonic missile on Tuesday. It has also fired ballistic missiles, and a cruise missile with potential nuclear capabilities, in recent weeks.

Pyongyang is under multiple international sanctions over its weapons programs, which have made rapid progress under Kim Jong-un, including missiles capable of reaching the whole of the US mainland and by far its most powerful nuclear test to date. 219
