North Korea boasts successful test of nuclear-capable underwater drone.

North Korea claims to have successfully tested a second type of nuclear-capable underwater attack drone, named "Haeil-2," designed to destroy naval vessels and ports. The test comes amid a flurry of weapons demonstrations this year that have heightened tensions with rivals. Analysts are skeptical about the device's effectiveness and whether it adds a meaningful new threat to North Korea's growing nuclear arsenal built around missiles. The US, South Korea, and Japan's nuclear envoys met in Seoul to discuss the growing North Korean nuclear threat and called for stronger international efforts to crack down on illicit North Korean activities funding its weapons program.
