Ukrainian anti-ship drones are hitting Russian tankers faster than the tankers hit in the Iran-Iraq War back in the 1980s, or even in the hottest weeks of the recent US-Iran War.

Operators from Ukraine's Unmanned Systems Forces struck eight tankers belonging to Russia's so-called shadow fleet in the Sea of Azov on the night of 6-7 July.

Ukrainian drones struck eight sanctioned fuel tankers, a ferry and a cargo ship.

Ukraine's military said on Tuesday that its drones struck eight tankers from Russia's 'shadow fleet' overnight as they were delivering fuel to Crimea.
