Documents include details on Ukrainian forces, U.S. arms provided to Ukraine

The Pentagon is investigating social-media posts that purport to reveal highly classified U.S. government documents on the war in Ukraine and other key international topics, in what could be one of the most dangerous intelligence breaches in decades.

Well over 100 images, marked with “Top Secret” and other classifications indicating they represent highly sensitive U.S.-produced intelligence, were posted in the Discord message board of fans of the Minecraft computer game around March 1. While many of them were deleted recently, open-source intelligence researchers have managed to download more than 60 files.
