“We are talking about a system of state terror," Stephen Rapp, former U.S. war crimes ambassador at large, said of how people lived in Syria under the Assad regime.

Mass graves uncovered in Syria in the days since President Bashar al-Assad was overthrown are exposing evidence of some of the worst abuses since the Nazis, a top international war crimes prosecutor said.

More than 100,000 people were tortured and killed in the state-run “machinery of death,” Stephen Rapp, former U.S. war crimes ambassador at large, told Reuters on Tuesday after visiting two mass grave sites in the towns of Qutayfah and Najha near Damascus.

“I don’t have much doubt about those kinds of numbers given what we’ve seen in these mass graves," said Rapp, who led prosecutions at both the Rwanda and Sierra Leone war crimes tribunals and is now working to help document evidence of war crimes in Syria.
