Rescuers detonate charges on Italian ship wreck Rescue squads have carried out controlled explosions on a cruise liner stricken off Italy's Tuscan coast. A total of eight microcharges were used. The explosions were to allow firefighters and scuba divers to get to parts of the ship that they were previously unable to access. Twenty-nine people are still missing: four crew members and 25 passengers. Authorities are looking for 14 Germans, six Italians, four French nationals and two Americans. The others are one each from India, Peru and Hungary. One crew member who made a dramatic escape was the ship's chief purser, Manrico Gianpetroni, who gave an interview to Italian television. "I was trapped in the restaurant when it happened," he said. Firemen took me and brought me here. Gianpetroni, who reportedly fell when trying to help other passengers, said he spent nearly 40 hours in freezing wet conditions before being rescued. Six bodies have been found so far. The vessel was carrying 4,200 people at the time of the accident, the vast majority of whom managed to flee the wreckage. The captain of the ship was arrested on Saturday on manslaughter charges and faced questioning from police earlier on Tuesday. He denies the charges. The cruise operators have blamed human error as the main cause of the crash.
