However, on 20 December the US informed Bangladesh that the cargo ship was not ‘Ursa Major’. Rather it is a ship named ‘Sparta 3’, which is under US embargo. Although the ship’s name and color have been changed, its IMO (International Marine Organisation) certificate number matches the IMO number of ‘Sparta-3’.
After confirming that the color and name of the ship carrying the Rooppur consignment had been changed, Bangladesh stopped it from anchoring in the port.
