The report said Kim urged researchers to develop artificial intelligence for the unmanned vehicles, and called to ramp up production of suicide drones, including those that can be used underwater, as well as reconnaissance and multi-purpose attack drones. South Korea’s Joint Chiefs of Staff said on Monday they were monitoring North Korea’s military activities and were prepared for any provocations. When asked about visual similarities between some of the drones in the images from Kim’s Saturday visit, and those used and produced by Russia, a spokesperson said more analysis was necessary.
