>> Heavy oil from a sunken tanker off China's coast could now be leaking into the sea. That's the fear from Chinese officials monitoring the worst oil ship disaster in years. Heavy oil is used in ships' engines and is difficult to remove from the sea. The cargo of lighter oil may also be leaking, with slicks spotted exceeding some 77 square miles.
The Iranian tanker had been adrift and ablaze after crashing into a freight ship on January 6th. The crew of 30 Iranians and 2 Bangladeshis are believed to have been killed. It's not immediately clear where any oil could wash up or the extent of damage it could cause. Experts say that to avoid further damage, the best option now is to salvage the ship, noting that the process will present huge risks and difficulties and that the remaining light oil could catch fire again.
