Russia’s Black Sea Fleet main ship Moskva was shot down by two Ukrainian Neptune missiles, a senior Pentagon official said on Friday.
Russia and Ukraine have provided various reports on how the Russian missile cruiser Moskva sank in the Black Sea.
Moscow claims a fire broke out on the ship, which caused the explosion of the ammunition it was carrying. Meanwhile, Ukraine claims to have attacked the strategically valuable ship through a missile attack.
But Pentagon officials backed the Ukrainian narrative, saying Kyiv forces used two Neptune anti-ship cruise missiles to hit the warship. No other details were given.
Ukraine says about 510 Russian sailors were aboard the Moskva when it was hit by its missile.
Russia said the Moskva had sunk in the storm as it was being towed to a port that was damaged by fires and explosions.
At least 1,982 civilians have been killed and 2,651 injured in Ukraine since the start of the war in late February, according to UN estimates, and the real figure is feared to be much higher.
More than 4.6 million Ukrainians have fled to other countries, with more than 7 million more internally displaced, the UN refugee agency says.
