Argentina missing submarine: Concern grows after two false alarms

Argentina's navy says it will take advantage of improved weather conditions to further step up its search for a submarine that vanished last Wednesday in the Atlantic Ocean. Strong winds and high waves have hampered the search for the ARA San Juan and its 44 crew in the past days.

Navy officials said that noises picked up by two search vessels did not come from the sub, dashing relatives' hopes for a speedy rescue. It was the second false alarm. A navy spokesman had earlier confirmed that satellite signals picked up on Saturday did not come from the missing boat.
