Salvage teams head towards the wreck of the Costa Concordia off the coast of the Italian island of Giglio.<br/> They are expected to use large external tanks into which they'll pump fuel from the stricken cruise liner.<br/> (SOUNDBITE) (Italian) FIRE BRIGADE COMMANDER, CLAUDIO CHIAVACCI, SAYING:<br/> "Today the salvage operation to pump the oil and fuel out of the tanks of capsized Concordia has started."<br/> The move will come as a relief to the island's residents, as fears of a fuel spill grow.<br/> If the ship's 2,400 tonnes of fuel and oil leak into the sea it would spark Italy's worst environmental disaster in over two decades.<br/> Officials say the amount of fuel on board the vessel is equivalent to that carried by a small oil tanker.<br/> At least 15 people were killed after the Costa Concordia ran aground and partially sank on January 13.<br/> Around 20 people are still unaccounted for.<br/> Travis Brecher, Reuters
