The United States is pushing for additional U.N. Security Council sanctions against North Korea following a series of recent missile launches, Washington's top envoy to the world body has said.

"On top of today's designations by @StateDept and @USTreasury, the U.S. is proposing @UN sanctions following North Korea's six ballistic missile launches since September 2021, each of which were in violation of UN Security Council resolutions," Linda Thomas-Greenfield wrote on Twitter.
