North Korea confirmed on Tuesday that it tested a new combat weapon system on Sunday, with leader Kim Jong-un calling it a demonstration of "ultra-modern" defense technology and warning that adversaries would face an "unavoidable blow." South Korea's Joint Chiefs of Staff had previously reported that Pyongyang fired two short-range ballistic missiles from the Wonsan area toward the East Sea, with screen imagery suggesting the weapon may be a newly developed hypersonic ballistic missile designated "Hwasongpho-11Ma-1." The launches, conducted days before a scheduled Washington summit between U.S. President Donald Trump and Chinese President Xi Jinping and on the eve of the UN General Assembly's high-level debate, are widely seen as a signal that Pyongyang has no intention of halting its military buildup despite mounting diplomatic pressure.
