Australia PM: Very confident signals are from black boxUpdated: 2014-04-11 16:31:25 (KST)
Authorities searching for Malaysia Airlines Flight 370 in the Indian Ocean believe they are on the right track.
Australian Prime Minister Tony Abbott told reporters in China he was very confident that the underwater "pings" recently detected are from the plane's black box.
Abbott did say though that the signal is starting to fade, and that it's crucial to recover the black box before its battery runs out.
That was about all Abbott said on the issue, adding that he didn't want to reveal too much until he'd had the opportunity to update the Chinese leadership later in the day.
