Ukraine War Plans Leak Prompts Pentagon Investigation

WASHINGTON — Classified war documents detailing secret American and NATO plans for building up the Ukrainian military ahead of a planned offensive against Russian troops were posted this week on social media channels, senior Biden administration officials said.
The Pentagon is investigating who may have been behind the leak of the documents, which appeared on Twitter and on Telegram, a platform with more than half a billion users that is widely available in Russia.
Military analysts said the documents appear to have been modified in certain parts from their original format, overstating American estimates of Ukrainian war dead and understating estimates of Russian troops killed.
