Ukrainian military officials said they struck the Moskva with Ukrainian-made Neptune missiles - a weapon designed after Russia's annexation of Crimea in 2014, and the naval threat to Ukraine in the Black Sea grew.
     The ship's sinking was described by the US as a "big blow", but American officials were unable to confirm whether Ukrainian Neptune missiles were responsible.
     "It's certainly plausible and possible that [Ukraine] did in fact hit this with a Neptune missile or maybe more," Pentagon spokesman John Kirby said to CNN.
     A senior Ukrainian official said as many as 510 crew could have been on board the Moskva.
     On the first day of Russia's invasion of Ukraine on 24 February, the Moskva gained notoriety after calling on a small garrison of Ukrainian border troops defending Snake Island in the Black Sea to surrender - to which they memorably radioed an expletive-laden message of refusal.
     Originally built in the Soviet-era, the Moskva entered service in the early 1980s. The vessel was actually laid down in Ukraine's southern city of Mykolaiv, which has been heavily bombed by Russia in recent days.
