Iran secretly delivered hundreds of thousands of shells to Russia, Sky News reports.

The source said two Russian-flagged cargo ships left an Iranian port in January bound for Russia via the Caspian Sea, carrying about 100 million rounds of ammunition and about 300,000 projectiles.

Ammunition for rocket launchers, mortars and machine guns would have been included in the shipments, and Moscow would have paid for the ammunition in cash, the quoted source claims.
