Argentina ends search for sub

ARGENTINA’S navy said Thursday that it is no longer looking for survivors among the 44 sailors aboard a submarine missing for 15 days, though a multinational operation will continue searching for the vessel.

Hopes of finding survivors already dimmed because experts said the crew only had enough oxygen to last 7 to 10 days if the sub remained intact under the sea. The navy also had said an explosion was detected near the time and place where the ARA San Juan made its last contact with shore Nov. 15.
