Pentagon press secretary John Kirby told CNN that “there was an explosion” on the Russian cruiser Moskva, but added the United States cannot assess at this point if the ship was hit by a missile.
Russia said its warship "remains afloat" after a fire detonated ammunition on board, while Ukrainian officials said the Moskva was hit by Ukrainian Neptune anti-ship missiles and has sunk.
“We’re not quite exactly sure what happened here. We do assess that there was an explosion — at least one explosion on this cruiser — a fairly major one at that, that has caused extensive damage to the ship,” Kirby said.
Kirby said the damaged Russian warship is afloat and "making her own way across the Black Sea."
“We assess that the ship is able to make its own way, and it is doing that; it's heading more towards now we think the east. We think it's probably going to be putting in at Sevastopol for repairs, but we don’t know what exactly caused that,” Kirby added.
Kirby said the ship had been operating with a few other Russian vessels about 60 miles (about 96 kilometers) south of Odesa.
"The explosion was sizable enough that we picked up indications that other naval vessels around her tried to come to her assistance, and so eventually that wasn’t apparently needed. So she is making her own way across the Black Sea and we’ll continue to try and monitor this as best we can," he added.
Meanwhile, US President Joe Biden's national security adviser Jake Sullivan said on Thursday that the battleship was badly damaged on Wednesday as a result of either “incompetence” or a successful attack by the Ukrainians.
“We’ve been in touch with the Ukrainians overnight who said they struck the ship with anti-ship missiles,” Sullivan told an audience at the Economic Club of Washington, DC “We don’t have the capacity at this point to independently verify that, but certainly the way that this unfolded is a big blow to Russia.”
“This is their flagship, the ‘Moscow,’ and they’ve now been forced to admit that it’s been badly damaged,” Sullivan continued. “And they’ve had to kind of choose between two stories. One story is that it was just incompetence, and the other is that they came under attack. And neither is a particularly good outcome for them.”
Sullivan said that when the president went to NATO a few weeks ago, he indicated to allies that the US was looking to facilitate the supply of coastal defense and anti-ship capabilities to the Ukrainians “and that is being actively worked.”
