North Korea tested another underwater nuclear attack drone
朝鲜再次测试水下核攻击无人机
North Korea on Saturday claimed it tested this week a second known type of nuclear-capable underwater attack drone designed to destroy naval vessels and ports, adding to a flurry of weapons demonstrations this year that have heightened tensions with rivals. The report of the four-day test came a day after the nuclear envoys of the United States, South Korea and Japan met in Seoul to discuss the growing North Korean nuclear threat.
朝鲜周六声称，它在本周测试了第二种已知的具有核能力的水下攻击无人机，旨在摧毁海军舰艇和港口，这为今年的一系列武器展示增加了新的内容，加剧了与对手的紧张关系。在美国、韩国和日本的核问题特使在首尔举行会议讨论日益严重的朝鲜核威胁的一天后，有关这次为期四天的试验的报告传来。
