Investigations Launched as Classified Military Documents Leak Online

The Pentagon and the Justice Department are investigating how secret military documents on the war in Ukraine appeared on multiple social media sites, including some marked "top secret." The breach raises questions about its extent and potential damage. The documents include assessments of China and countries in the Middle East, maps of Ukraine, and charts on troop concentration and weapons availability. Some documents are dated to late February or early March and appear to be part of a slide deck produced daily for top U.S. military and other national security officials. The original source for posting the documents online has not been publicly identified, and the motive for putting the material online is unclear. A senior advisor to Ukraine's President believes Russia is responsible.
