Argentine submarine latest: Sound detected during search for missing vessel 'consistent with explosion' ARA San Juan latest: Argentina say detected sound in missing submarine search consistent with explosion
(35 minutes later)
Argentina has said the sound detected in search for missing submarine is consistent with an explosion'.  A sound detected in the search for the missing submarine carrying 44 people is 'consistent with an explosion,' Argentine officials have said.
The abnormal sound was detected in the South Atlantic ocean around the time that an Argentine navy submarine sent its last signal last week. The abnormal sound was detected in the South Atlantic ocean around the time the Argentine navy submarine sent its last communication last week.
Navy spokesman Enrique Balbi described the blast in the morning of 15 November as “abnormal, singular, short, violent” and “non-nuclear.” A huge sea and air hunt is being conducted for the ARA San Juan, which went missing with 44 crew on board.  Navy spokesman Enrique Balbi described the blast as “abnormal, singular, short, violent” and “non-nuclear". The "hydro-acoustic anomaly," as officials are calling it, occurred just hours after the Navy lost contact with its vessel on 15 November.
"It was not a whale, and it is not a regularly occurring sound," US Navy Lieutenant Lily Hinz told Reuters.
Argentina, Brazil, and the US have sent ships and planes to investigate the noise, which occurred about 30 miles from where the submarine disappeared.
A huge sea and air hunt is being conducted for the ARA San Juan. More than a dozen countries sent planes and ships to aid in the search, which has covered some 185,000 square miles. The UK's Ministry of Defence sent a special helicopter equipped with emergency life support pods to search for the German-built sub.
Experts say the vessel may only have enough oxygen to last seven to 10 days after its disappearance more than a week ago. Families are waiting anxiously for updates at Argentina's Mar del Plata navy base, where the submarine was headed before it vanished.
Mr Balbi said relatives of the crew have been informed of the abnormal noise. He added that the search will continue until there is more certainty as to the vessel's fate.
The families' hopes were momentarily raised earlier this week when a US Navy search plane detected an object in the water near where the submarine disappeared. A spokeswoman for the US embassy in Argentina later confirmed the object was not connected to the ARA San Juan.
