South Korea’s military says North Korea fired a projectile toward the sea

SEOUL – North Korea on Monday fired at least one projectile toward its eastern waters, South Korea’s military said, adding to a recent streak of weapons demonstrations that has heightened tensions during a prolonged freeze in diplomacy.

South Korea’s Joint Chiefs of Staff did not immediately say whether the weapon was ballistic or how far it flew. Japan’s Defense Ministry said it detected at least two suspected ballistic missile launches and assessed that the weapons landed in waters outside the country’s exclusive economic zone.

The launch came days after South Korea on Friday flight-tested its first domestically developed hypersonic weapon, designed to fly at least five times the speed of sound and evade missile defense systems, which President Lee Jae Myung described as an important step in strengthening the South’s conventional defense capabilities.

While maintaining a hard line toward Seoul, North Korea has been ramping up weapons testing as it seeks to expand its arsenal of nuclear-capable systems, including an Oct. 3 test of what the North described as a hypersonic intermediate-range missile designed to evade missile defenses in South Korea and Japan.

North Korea has also conducted other missile tests and live-fire drills and commissioned a new warship as leader Kim Jong Un continues to flaunt his nuclear weapons program while rejecting U.S. and South Korean offers to resume long-stalled diplomacy.

Tensions were further worsened after three South Korean soldiers were injured in land mine explosions last month near the heavily armed inter-Korean border. The South’s military and the U.S.-led United Nations Command concluded the blasts were caused by devices planted by North Korea, which has denied responsibility and ridiculed the South’s demands for an apology.

Kim in recent years has halted all diplomacy and cooperation with South Korea and described the neighbor as a permanent enemy during a prolonged stalemate in larger nuclear negotiations with Washington. He has so far rebuffed U.S. President Donald Trump’s calls to revive their diplomacy, which broke down in 2019, with his government demanding that Washington abandon its “hostile” policy toward Pyongyang and drop demands for North Korea’s denuclearization as a precondition for talks.

The tensions have been a setback for Lee, who favors engagement with North Korea and has tempered his rhetoric toward the North even as public anger grows over the mine blasts. Lee has also called for strengthening South Korea’s conventional defense capabilities while reducing its reliance on the United States. Washington unilaterally decided to scale back a major military exercise with South Korea in August, with Trump citing his “very good relationship” with Kim.
