All four American marines accused of urinating on corpses in Afghanistan have been identified and two of them have been interviewed, according to the US military.
A spokesman said two of the men "have been questioned" by the Naval Criminal Investigative Service over the footage, but were "not in custody".
The marines are from a sniper unit based at Camp Lejeune in North Carolina. The two questioned are on active duty. It took longer to locate the other two because they had been transferred from Camp Lejeune before the video emerged.
Investigators are also trying to identify and question the person who filmed the scene.
The marines were deployed in south-western Afghanistan from March to September last year. It was not certain whether the dead were Taliban fighters or civilians.
Hillary Clinton, the US secretary of state, said the culprits would be punished. As well as a court martial, they could face war crimes charges as the Geneva Convention prohibits the desecration of enemy remains. (© Daily Telegraph, London)
