The Iranian tanker, Sanchi, has been ablaze since it collided with Hong-Kong registered freight ship CF Crystal on the evening of January 13th, 185 miles off China's coast near Shanghai. Since the crash, the tanker has been billowing thick plumes of black smoke. Sanchi was carrying almost one million barrels of highly flammable crude oil to South Korea with 32 crew members on board - 30 Iranians and two Bangladeshis. All are missing, but the body of a mariner suspected to be from the ship was recovered on Monday. The 21 Chinese crew members on the CF Crystal, carrying grain from the US, were rescued. Ten foot waves and strong winds, along with toxic fumes from the burning oil, have also been hindering the efforts to extinguish the fire.
