Italian Coast Guard divers have found a woman's body in a corridor of a submerged section of the "Costa Concordia" on Jan 21, raising to at least 12 the number of dead.

 The body, wearing a life jacket, was found in a narrow corridor near an evacuation staging point at the ship's rear.

 The body was brought to Giglio. Twenty persons are still missing. Some divers are going from cabin to cabin and leaving cameras in each room for about 45 minutes.

To make entering and exiting the ship easier, divers have blasted more holes into the hull of the vessel.

Italian officials have confirmed the presence of light fuel in the sea around the wreck.

It was believed that the fuel may have come from the ship's machinery. The light fuel substance detected near the ship appeared to be diesel, used as a fuel for rescue boats and dinghies as well as a lubricant for ship machinery.
