The UK and Argentina have signed a deal to identify 123 Argentine soldiers buried on the Falkland Islands.
The International Committee of the Red Cross has been negotiating an agreement on taking DNA samples from the remains of men who died in the 1982 conflict.
The graves in the Argentine memorial cemetery, in Darwin, are currently marked as "soldier only known to God".
The two-month conflict saw 649 Argentine soldiers killed, while 255 British service personnel died.
The conflict saw a taskforce recapture the British overseas territory in the South Atlantic after an invasion by Argentina.
In total, 237 Argentine soldiers are buried in the cemetery. The work on identifying the unknown men is expected to take place between June and August next year, according to a report on the Argentine news agency Telam.
