The Pyongyang-supplied missiles with ranges of around 900 kilometers (550 miles) were fired by Russia in two attacks within the past week, National Security Council spokesman John Kirby said. "Our information indicates that the Democratic People's Republic of Korea recently provided Russia with ballistic missile launchers and several ballistic missiles," Kirby told reporters in a briefing at the White House. The development underscored the need for the US Congress to pass a package of vital military aid for Ukraine, without which the pipeline of support will soon run dry, Kirby added.
