Intelligence Leak Sparks Crisis Mode for U.S. and Allies over Ukraine War.

Senior US officials are trying to calm down allies from Europe to the Middle East to Kyiv after the leak of highly classified information about the war in Ukraine and other global issues. Members of the Five Eyes have asked for briefings from Washington but have yet to receive a substantive response. The majority of the documents focus on the war in Ukraine, which the US has repeatedly said hinges on collaboration among allies in NATO, Europe, and elsewhere. The leak has left the US relationship with its allies in a state of crisis, raising questions about how Washington will correct what officials worldwide view as one of the largest public breaches of US intelligence since WikiLeaks.
