Aug. 24 (UPI) -- North Korea has test-fired two missiles newly designed to protect against aerial attacks, overseen by leader Kim Jong Un, state media announced Sunday.

The supreme leader oversaw the missile tests along with multiple members of the Workers' Party of Korea and military officials, the Korea Central News Agency reported. The outlet said the missiles have "superior combat capability" and a "fast response" to attacks from aerial targets such as drones and cruise missiles.

The testing came less than a week after Ulchi Freedom Shield 25, joint military exercises between the United States and South Korea, ABC News reported. The annual training exercises began Monday and were expected to end Thursday.

The training was expected to include live-fly events with U.S. F-35A and F-35C Lightning II aircraft as well as space-related elements, the Defense Department said. The Pentagon said the exercises work to strengthen the agencies' response capabilities.
