'Only defeat': Leaked Russian FSB report identifies Ukraine invasion as a 'total failure'

Russia's war with Ukraine will result in "total failure" and could spark the threat of international conflict, an FSB whistleblower has claimed in a leaked report.

An anonymous FSB official reportedly leaked the document which revealed the intelligence agency was left in the dark over Russia's invasion of Ukraine and was unprepared to deal with the crippling sanctions that followed.

The Federal Security Service, or FSB, is the main successor agency to the Soviet-era KGB.
