SEOUL, SOUTH KOREA — North Korea said Tuesday its latest weapons test was a new hypersonic intermediate-range missile designed to strike remote targets in the Pacific as leader Kim Jong Un vowed to further expand his collection of nuclear-capable weapons to counter rival nations. The North Korean state media report came a day after South Korea’s military said it detected North Korea launching a missile that flew 1,100 kilometers (685 miles) before landing in waters between the Korean Peninsula and Japan. The launch, conducted weeks before Donald Trump returns as U.S. president, came off a torrid year in weapons testing.
