The U.S. has vehemently refuted new claims that the missing Malaysia Airlines Flight MH370 landed in Diego Garcia, an island situated south of the equator of the Central Indian Ocean.

After the Flight MH370's disappearance on March 8, there were increasing difficulties in searching for the jetliner. Several theories and speculations surfaced. One of the recent speculations suggested the missing Flight MH370 could have landed in Diego Garcia. But a spokesman of the U.S. embassy based in Malaysia denied such claims, The Mirror reported.

"There was no indication that MH370 flew anywhere near Maldives or Diego Garcia."

The spokesman said the missing jetliner "did not land in Diego Garcia." He added the U.S authorities are working with Malaysia and Australia and other countries who are striving hard to locate the Malaysian Flight MH370 based on the areas identified by the Malaysian and other international aviation officials.

Meanwhile, Australia's Prime Minister Tony Abbott is confident the signals or pings recently detected in the Indian Ocean were from the Malaysia Airlines Flight MH370, The Telegraph reported.

During Abbott's visit to China, he told the media reporters the search team had detected a series of pings and signals that could pertain to the jetliner's black box. He said the recent findings have helped them narrowed down the search.

"We're getting to the stage where the signal from what we are very confident is the black box is starting to fade," Abbott added.

"We are hoping to get as much information as we can before the signal finally expire," he noted.

A plane's black box can apparently emit signals for 30 days before the built-in battery dies down. Some experts said a black box can continue to work for two more weeks but it depends on the condition of the batteries installed to it. It has been more than 30 days since the Malaysia Airlines Flight MH370 has disappeared, with a total of 239 passengers on board. Up to this day, there are still no significant leads that could tell the whereabouts of the jetliner.

Abbott and the rest of the search team are optimistic they are close to finding the black box that could somehow shed a light on the mystery.

He said they are certain that the black box is situated "within some kilometers." But still, it wouldn't be enough to fully explain the fate of the missing jetliner.
