"There is not the slightest doubt that the attack was planned in advance using Western intelligence assets, NATO satellite equipment, and reconnaissance aircraft," Russian foreign ministry spokeswoman Maria Zakharova said.

The missile strike was carried out "in close coordination with the American and British intelligence services," she added.

Ukraine claimed responsibility for a missile attack that on Friday struck the headquarters of Moscow's Black Sea Fleet in annexed Crimea, sparking a huge fire.

Moscow said that the attack left one Russian serviceman missing, while Kyiv claimed that the strike killed thirty-four officers including the fleet commander, Viktor Sokolov.

Moscow has however denied the claim.

Undated footage broadcast Wednesday by the Russian defence ministry's Zvezda TV channel showed Sokolov saying that the Black Sea Fleet was "fulfilling the tasks the command has set."

Since sending troops to Ukraine in February 2022, the Kremlin has accused Western powers of de-facto fighting against Moscow by providing financial and military support to Kyiv.
