North Korea conducted another test of a nuclear-capable underwater attack drone, state media said on Saturday (April 8), the latest in a show of force against the U.S. and South Korea, Reuters reports.
Still photographs aired by state broadcaster KRT showed the drone manoeuvering across the surface of a body of water and then fully underwater, as well as a target being exploded.
During the underwater strategic weapon system test from April 4 to April 7, KRT said that the drone, called the "Haeil-2", cruised 1,000 km (621.37 miles) of underwater distance for 71 hours and 6 minutes.
North Korea's new test of an underwater attack drone comes over a week after it first disclosed a system dubbed "Haeil-1", which translates to tsunami in Korean, designed to make sneak attacks in enemy waters.
