SURABAYA, Indonesia (AP) — Indonesian rescuers searched for possible missing passengers Monday after rescuing 231 people from a ferry that caught fire the previous day off the main island of Java, leaving at least five people dead. However, by Monday officials said many more people were aboard than listed, and the number of people missing was unclear. Officials were relying on reports from families of victims and survivors in an attempt to determine the number of the missing. It is common in Indonesia for the number of passengers on a boat or ferry to differ from the manifest. Such discrepancies can complicate search and rescue efforts, said Nanang Sigit, the search mission coordinator who also heads the Surabaya Search and Rescue Office.
