Argentina's navy says fresh noises are not from missing submarine

Argentina’s navy has said sounds detected from the bottom of the ocean are not from the submarine which has been missing in rough seas for five days with 44 crew on board. Spokesman Enrique Balbi said “a biological source” was behind the noises which were picked up by two Argentinian navy ships searching for ARA San Juan and by sonar buoys dropped by a US P8 surveillance plane.
