A Russian cargo ship that Ukraine claims was sent to Syria to collect weapons has sunk in the Mediterranean Sea, according to officials in Moscow. Two crew members are missing after an engine room explosion sank the Ursa Major between Spain and Algeria, the foreign ministry said. Fourteen other crew were rescued and taken to Spain. Ukraine's military intelligence claimed yesterday that the ship, previously called Sparta III, had been sent to Syria to remove weapons and military equipment after the fall of Bashar al Assad.
