The apparent leak of a trove of highly classified US documents including many related to the Ukraine conflict has triggered a criminal investigation as well as a multi-agency effort to assess the potential fallout. The source of the leaked documents is unknown and as of Monday the Department of Defense was still working to assess their authenticity, though it has acknowledged they appear to contain sensitive, classified material.
U.S. officials have briefed allies and partners, including Canada, about the leak, which reportedly show attempts by Russia to hack Canada’s natural gas infrastructure.
The online leaks of scores of highly classified documents about the Ukraine war present a very serious risk to national security, a top Pentagon spokesman said on Monday.
The U.S. officials declined to provide any specifics, including about the expanse of the release, how it happened and to which country leaders the U.S. has spoken.
A chatroom on Discord, a popular social media platform, is suspected to be the source of a major leak of classified U.S. documents that has caused a stir.
