The Argentine navy says it has abandoned attempts to rescue 44 crew members on board a submarine that disappeared two weeks ago.
"Despite the magnitude of the efforts made, it has not been possible to locate the submarine," navy spokesman Enrique Balbi said on Thursday.
The sub, the ARA San Juan, last made contact on Wednesday 15 November.
Hopes of finding survivors faded after a suspected explosion was reported near its last-known location
The ARA San Juan was returning from a routine mission to Ushuaia, near the southernmost tip of South America, when it reported an "electrical breakdown".
The submarine, with its 44 crew, set off under the command of Pedro Martín Fernández.
Forty-three of the crew were men but there was also one woman, Eliana María Krawczyk. The 35-year-old was the first female officer in Argentina to serve on a submarine.
The rest of the crew were submariners of varying ages and experience.
