Ukraine has mocked the Kremlin after releasing footage that appears to show its Neptune missile mobile launches that sank Russia's Moskva cruiser - the flagship of Vladimir Putin's Black Sea fleet - one year ago today.

Kyiv's officials taunted their Russian counterparts over the footage which claims to show missiles launching and blasting into the sky on their way to sink the Moskva in the Black Sea.

The flagship was caught in a fiery blaze after being inflicted with significant damage to its left side as a thick plume of black smoke cascaded from the vessel and into the sky. The Moskava sank on April 14 of last year, and now sits some 150ft beneath the water's surface after being struck by the two Neptune missiles. 

Ukraine's defence minister Oleksiy Reznikov used the anniversary to ridicule the Kremlin, saying 'I invite you to visit a new dive spot' to visit the wreck of Putin's treasured warship.

Russia has since tried to cover-up the attack - one of its biggest humiliations of the war - refusing to ever reveal how many died or the command failures that led to the vessel's loss.
