Sounds did not come from missing submarine, says Argentine navy

Sounds detected by probes deep in the South Atlantic did not come from an Argentine submarine that has been lost for five days, the country's navy said, dashing newfound hope among relatives of the 44 sailors aboard.

Navy spokesman Enrique Balbi told reporters that the "noise" was analysed and experts determined it was likely "biological". He said the sounds did not come from tools being banged against the hull of a submarine as was previously reported by some media.
