North Korean leader Kim Jong Un inspected "suicide attack drones" under development on Thursday and watched tests involving strikes on a mock tank and BMW sedan, according to state media, in a preview of how the DPRK could use such weapons in conflict on the peninsula.

Kim also called on officials to "quickly establish a mass-production system and begin full-scale production as soon as possible," the Rodong Sinmun reported on Friday, amid suspicions that Pyongyang is receiving technical assistance from Russia.
