North Korea has conducted another test of a nuclear-capable underwater attack drone, its state media reported on Saturday, the latest demonstration of its military capabilities as it faces off against the United States and South Korea.
North Korea tested a nuclear-capable unmanned underwater attack weapon called "Haeil-2" from April 4 to April 7, state media reported, more than a week after it disclosed a new underwater drone called "Haeil-1", which translates as tsunami.
