An alleged arms contract appears to offer the first hard evidence that Iran has sold ammunition to Russia for its war in Ukraine.
The 16-page document, dated to September last year, apparently shows orders worth almost a million euro.
The authenticity of the papers have not yet been verified independently.
Sky's security and defence editor Deborah Haynes has more:
"It's says it's a contract between Iran's Ministry of Defence and also the Russian export and import company. They believe it's samples of different types of ammunition, rounds for artillery guns, and for tanks".
