South Korea says North Korea has launched an additional projectile toward the sea

SEOUL – North Korea launched a short-range ballistic missile toward the sea on Sunday, South Korea's military said, two days after the North threatened to bolster its nuclear deterrent capabilities and respond to what it called U.S. hostilities.

South Korea's military said the missile flew about 450 kilometers (280 miles) toward the North’s eastern waters.

Hours later, it said the North launched another projectile off its eastern coast but gave no further details as to what type of weapon it was. The South Korean military said it has boosted its surveillance posture and was closely exchanging information on the launch with the United States and Japan.

South Korea's presidential office urged North Korea to immediately halt ballistic missile launches that are banned by U.N. Security Council resolutions. It said South Korea held an emergency national security council meeting to discuss the launch.

Japan's Defense Ministry said it noted a suspected North Korean missile earlier Sunday but that the missile did not land in its territorial waters. It did not elaborate on where it landed.

The launches came as North Korea is engaging in a run of weapons tests even after U.S. President Donald Trump scaled back a military exercise with South Korea last month in an apparent effort to revive diplomacy with leader Kim Jong Un.

Kim's sister and senior official, Kim Yo Jong, shrugged off Trump’s overture, saying that shortening the drill wouldn’t change its “provocative, aggressive nature.” North Korea’s military later launched about 10 short-range ballistic missiles toward the sea, apparently following through with a previous threat to respond to the U.S.-South Korean drill.

On Friday, Kim's sister slammed another recent U.S.-led multilateral maritime exercise in the region as a “frantic military move” by the Americans meant to prolong their hegemony in the Asia-Pacific area. The “Pacific Vanguard” exercise brought together the U.S., South Korea, Japan, Australia, New Zealand and Canada.

She claimed that “regular U.S.-led war rehearsals” are the main source of worsening tensions in the Korean Peninsula and the region.

“Our will to defend our sovereignty will be expressed in clearer action and there will be never ever change in the course of intensifying the nuclear war deterrence,” she said.

Earlier this month, North Korea conducted what it called a joint live-fire drill involving missiles, artillery and drones, a day after the United States, South Korea and Japan wrapped their five-day trilateral military drill that North Korea described as a provocation. North Korea said its drill included firing different types of weapons simultaneously, likely aiming at developing the ability to overwhelm South Korean and U.S. air defenses.

Kim Jong Un has been focusing on expanding his nuclear arsenal after his earlier high-stakes diplomacy with Trump collapsed in 2019. When Trump ordered the Pentagon to “substantially reduce” the annual Ulchi Freedom Shield exercise with South Korea, he cited what he called a good relationship with Kim, who has called such drills invasion rehearsals.

Emboldened by his advancing nuclear arsenal and deepening ties with Russia and China, experts say Kim likely thinks he now has greater leverage in possible fresh diplomacy with Trump. Earlier this year, Kim said he could return to talks if the U.S. drops its “hostile policy” against his country and respects what he calls the North’s status as a nuclear state.
