Zero visibility prevented Indonesian Navy divers Sunday from reaching large objects believed to be parts of an AirAsia plane that crashed with 162 people last week, the search chief said, according to dpa. Rescue officials said Saturday that ships equipped with sonar technology had detected four large objects they hoped were parts of AirAsia's Airbus A320-200 fuselage. "Today we sent two divers with the aim of reaching the biggest object, but visibility on the sea floor was zero and it was covered with mud," search chief Bambang Sulistyo said. "So the effort was suspended." A remotely operated undersea vehicle would be sent instead, he said. Bambang said searchers detected another object on the sea floor near the other four objects found earlier. Bambang said another body was found, bringing the confirmed death toll to 31. The aircraft went down during a flight from Surabaya, Indonesia's second-largest city, to Singapore on December 28.
