The two missiles tested on Saturday were designed to target aerial threats, including attack drones and cruise missiles, the Korea Central News Agency reported on Sunday.

The newly-tested air-defense missiles "are very suitable for destroying various aerial targets," North Korean state media reported.

North Korea accused South Korea of a “dangerous provocation” during a recent incident at the border of the two countries, adding to tensions as Pyongyang chafes at the annual joint US-South Korean military drills that are underway.
