PERTH, Australia —
In Malaysia, Defense Minister Hishammuddin Hussein on Saturday refuted a front-page report in a local newspaper, the New Strait Times, that a signal from the mobile phone of co-pilot Fariq Abdul Hamid was picked up by a telecommunications tower near the Malaysian city of Penang shortly before the plane disappeared from radar. The newspaper report said the signal ended abruptly before contact was established.
Hishammuddin, who is also the acting transport minister, told the Malaysian national news agency Bernama that he should have been aware of the phone call earlier, but that wasn't the case.
"I cannot comment (on the newspaper report) because if it is true, we would have known about it much earlier," Hishammuddin said after praying at a mosque in southern Jofor state, according to Bernama.
He added that it was irresponsible for anyone to take the opportunity to make "baseless" reports.
Four sounds heard April 5 and April 8 by the Australian ship Ocean Shield, which was towing the ping locator, were determined to be consistent with signals emitted from the two black boxes.
"Given that the signal from the black box is rapidly fading, what we are now doing is trying to get as many detections as we can so that we can narrow the search area down to as small an area as possible," Abbott said.
The underwater search zone is currently a 1,300-square-kilometer (500-square-mile) patch of the seabed, about the size of Los Angeles.
The searchers want to pinpoint the exact location of the source of the sounds — or as close as they can get — before sending the sub down. It will not be deployed until officials are confident that no other electronic signals are present.
The Bluefin 21 submersible takes six times longer to cover the same area as the ping locator, and will need about six weeks to two months to canvass the current underwater zone. The signals are also coming from 4,500 meters (15,000 feet) below the surface, which is the deepest the Bluefin can dive.
The surface area being searched on Sunday for floating debris was 57,506 square kilometers (22,203 square miles) of ocean extending about 2,200 kilometers (1,367 miles) northwest of Perth. Up to 12 planes and 14 ships were participating in the hunt.
