SEOUL, South Korea — North Korea said on Sunday that the two projectiles it fired a day earlier were a new type of missile, making this the third new short-range ballistic missile or rocket system the North has successfully tested in less than a month as Washington struggles to resume talks on denuclearization.



The two missiles were launched off North Korea’s east coast on Saturday in its second weapons test in the past week. On Sunday, North Korea’s official Korean Central News Agency released photographs of Kim Jong-un, the North Korean leader, watching what it called the launching of “another new weapon system.”

After scrutinizing the photos, outside analysts said the missiles, fired from a tracked mobile launcher with two missile tubes, were of a type unveiled for the first time.

North Korea has conducted five weapons tests since July 25, all of them in violation of United Nations resolutions, according to South Korea. They include a new short-range ballistic missile, known as KN-23 among outside analysts, which they said resembled Russia’s Iskander missile in its flight pattern and other traits. The North also tested a new multiple-tube rocket launcher.
