Rough waves crash against Italy's Giglio Island - and the stricken hull of the Costa Concordia cruise ship.<br/> <br />Bad weather has again halted rescue and salvage effort, and tangled parts of the floating protective barrier around the boat.<br/> <br />Crews were hoping to start pumping more than 2,300 tonnes of diesel fuel from the capsized ship this week before it leaks into the water.<br/> <br />But they can't begin until the sea calms.<br/> <br />Pumping the fuel could take up to a month to complete, while the actual salvage operations may span almost a year.<br/> <br />Crews are also watching the hull's movements as it shifts in rough waters.<br/> <br />Jessica Gray, Reuters
