Search for missing sub accelerates

BUENOS AIRES, Argentina–The round-the-clock international search for a submarine that has been lost in the South Atlantic for nine days is accelerating amid growing fears for its 44 crew members.
The Argentine navy says an explosion occurred near the time and place where the sub went missing on Nov. 15.
That’s led some family members of the crew to give up hope of a rescue.
Navy officials and outside experts worry that even if the ARA San Juan is intact but submerged, its crew may be running out of oxygen.
The German-built diesel-electric TR-1700 class submarine was commissioned in 1985 and most was recently refitted in 2014.
Some relatives of the crew have lashed out at the navy for its response and for putting their loved ones at risk in a vessel that is more than 30 years old.
