A leaked trove of classified documents outlining American and NATO war planning in Ukraine has sparked a US military investigation, the New York Times has reported. The briefing presentation slides, some marked “top secret,” show assessed troop strengths, timelines for arms shipments and ammunition expenditures, among other data.
The files appeared on social media earlier this week, and while the source remains unclear, the leaks have set off alarms in the Pentagon, which has launched a probe to determine how the documents were obtained, the NYT reported on Thursday.
“We are aware of the reports of social media posts and the department is reviewing the matter,” Pentagon spokesperson Sabrina Singh told the outlet.
Officials said they are working to have the material removed from the internet, but had not succeeded as of Thursday night.
