Italian officials say all remaining passengers have been taken off the ferry Norman Atlantic, which caught fire off the island of Corfu. It is unclear what caused the fire to break out yesterday on the car deck of the ferry, which was carrying 478 people from the Greek city of Patras to Ancona in Italy. Five people died in the incident. More than 400 people were rescued, in a long and complex operation amid gale-force winds and thick smoke. Italian prosecutors announced on Monday that they had opened a criminal investigation into the fire and would look into whether negligence had played a role.
