North Korean leader Kim Jong Un has overseen the testing of a new type of "anti-aircraft weapon system," state media reported Sunday, as the reclusive nation continues its arms testing and development.

The latest weapons test comes after a spate of missile launches, military drills and threats from the Pyongyang as the U.S. seeks to tighten the screws on the North.

The official Korean Central News Agency said Kim "watched the test of new-type anti-aircraft guided weapon system" that was aimed at "detecting and striking different targets flying from any direction." The KCNA report did not give a date or location for the test.
