North Korea launched a ballistic missile into the sea on Sunday, its neighbors said, in a resumption of weapons tests that came as the United States and its allies are focused on Russia's invasion of Ukraine.
The North Korean launch was the eighth of its kind this year and the first since Jan. 30. Some experts have said North Korea is trying to perfect its weapons technology and pressure the United States into offering concessions like sanctions relief amid long-stalled disarmament talks. They say North Korea also might view the U.S. preoccupation with the Ukraine conflict as a chance to accelerate testing activity without any serious response from Washington.
