A German container ship rescued 75 passengers from a sinking passenger ship off the coast of Tanzania today, dpa cited a spokesman for the German ship's operators saying. He said the MS Dorian responded to an SOS from the stricken vessel after other ships in the vicinity declined to provide assistance, fearing the call was a trap set by pirates. The incident happened in an area where pirates have often attacked commercial shipping and held their crews for ransom. The captain of the German vessel radioed international shipping authorities in London to confirm the identity of the sinking passenger ship, the Ile D'Anjouan. When he was given the all clear, he set course for the ship, which he reached four hours later, the spokesman for the German shipping operator Komrowski said.
