The United States provided intelligence to Ukraine to help sink the Russian flagship Moskva, according to U.S. officials, drawing a direct link between the Biden administration and one of the biggest blows to the Russian military since its invasion began in late February.

The U.S. identified the vessel and provided its location after Ukrainian officials inquired about a ship sailing in the Black Sea in mid-April, U.S. officials told NBC News. Ukrainian forces then hit the ship with two Neptune missiles, and it sank the next day, April 14.
