More than 800 people were plucked from a sinking ferry in the southern Philippines on Sunday, but at least three were killed and 88 remained unaccounted for, the coastguard said, according to Reuters. The "Superferry 9" vessel was carrying about 960 passengers and crew when it set off from General Santos City, on the southern island of Mindanao, for the central city of Iloilo. It began listing early on Sunday morning, prompting authorities to sound a general alert and rush rescue vessels to the area, coastguard commander Admiral Wilfredo Tamayo told reporters. A total of 870 passengers were rescued and brought ashore on other ships, he said. Eighty-eight were unaccounted for but most were likely to have been rescued by a fleet of fishing vessels and small boats that also came to the area, he said. Three people died due to exposure, Tamayo said. The weather was clear at the time, but the crew had reported problems with the generator, he added. Ferries are an important mode of transport in the Philippines, an archipelago of more than 7,000 islands. But their safety record is abysmal, and many accidents occur because of overcrowding or poor maintenance.
