A former Bosnian Serb soldier accused of involvement in the 1995 Srebrenica massacre has been charged by a US court with immigration fraud.
Boskic faces up to 45 years if convicted on all charges
Marko Boskic is accused of twice denying his role in the massacre when filing immigration papers. He entered the US as a refugee four years ago.
More than 7,000 Muslim men and boys were slaughtered at Srebrenica.
If convicted, Mr Boskic faces a lengthy prison term and possible deportation to Bosnia. He was arrested on 25 August.
The US attorney for Massachusetts - where the case will be tried - said the charges sent a "clear, unmistakable message" that those who take innocent lives will be found and prosecuted.
"The repulsive crime that underlies this case is simply unimaginable," said attorney Michael Sullivan.
Remains have been collected from mass graves around Srebrenica
Mr Boskic, 40, was arrested at his condominium in a Boston suburb, where he had been working as a construction worker.
The Srebrenica massacre was Europe's worst atrocity since World War II.
In July 1995 Bosnian Serb forces walked past Dutch UN peacekeepers supposed to be guarding the people of Srebrenica, separated the Muslim men and boys from their female relatives, and killed more than 7,000 of them.
