North Korean leader Kim Jong Un observed tests of newly developed reconnaissance and attack drones this week and called for their increased production, State media said on Thursday.

Kim has been emphasising the development of drones and the tests were the latest display of his country’s growing military capabilities.

Photos released by North Korea’s official Korean Central News Agency showed Kim observing what appeared to be a large reconnaissance drone roughly resembling Boeing’s E-7 Wedgetail airborne warning and control aircraft.
