Satellite calls did not come from missing Argentina submarine
Argentina's navy says that brief satellite calls did not come from a missing submarine with 44 crew members on board.
The communication attempts received were originally thought to indicate that the crew was trying to re-establish contact and had prompted celebrations by family members and officials.
But Navy spokesman Enrique Balbi said on Monday that the seven low-frequency satellite signals were analysed and do not correspond to the submarine, the ARA San Juan.
Authorities last had contact with the sub on Wednesday as it was sailing from the extreme southern port of Ushuaia to the city of Mar del Plata.
Admiral Gabriel Gonzalez of the Mar del Plata Naval Base said on Monday that the submarine had sent an alert on Wednesday about an unspecified breakdown.
