On November 15, the ARA San Juan, an Argentine submarine, went missing at sea with 44 crew-members on board.
Since then over a dozen countries, including the US and Russia, have sent assistance to locate the submarine.
On November 24, the Argentine Navy said that a suspected explosion was detected in the south Atlantic last week, dashing any hopes of the submarine's survival.
How did Argentine submarine San Juan go missing?
Submarine had reported "electrical breakdown"
The ARA San Juan had surfaced and reported an "electrical breakdown" while returning from a routine mission to Ushuaia, South America's southern-most tip.
The submarine was ordered to return to an Argentine naval base immediately.
On November 15, it reported that the problem had been sufficiently fixed and that it would submerge and head to the base.
This was the last contact with submarine.
Explosion reported close to submarine's last known location
The Argentine Navy said two hydro-acoustic stations of a Vienna-based nuclear weapons watchdog had detected a signal from an "underwater impulsive event."
The US also reported a "hydro-acoustic anomaly" hours after the submarine's disappearance.
The Argentine Navy said these explosions took place close to the vessel's last known location.
Search efforts are now being concentrated in that area.
