Forensic experts have found remains of a person thought to have been held in Uruguay's military rule, for the first time in government-led excavations.
President Vazquez (left] ordered the military to identify burial sites
The finding took place at a farm near Montevideo, where the air force says two Communist activists are buried.
Around 180 Uruguayans are known to have been killed during the 12-year military rule that ended 20 years ago.
Only 36 of them died in Uruguay. The rest were killed in neighbouring countries, chiefly in Argentina.
Bill on debate
Until now there had been no official investigation in Uruguay into the 1973-1985 military rule.
Correspondents say left-leaning president Tabare Vazquez has promised to change that. On taking office in March he ordered the armed forces to identify possible burial sites.
Mr Vazquez visited the excavation site on Tuesday.
He said the remains now uncovered have yet to be identified, but he promised to continue with the investigations, to reveal the full story of abuses committed by the military.
The find came as the Uruguayan parliament started debating a bill that could allow more prosecutions. At present an amnesty law protects military officers in Uruguay.
