GENEVA (Reuters) - War crimes investigators and activists have amassed an "overwhelming volume" of testimony, images and videos documenting atrocities committed by all sides during Syria's war, a U.N. quasi-prosecutorial body said in its first report.

The team, led by former French judge Catherine Marchi-Uhel, said it is preparing case files and has engaged with war crimes investigative units of various states including in Europe, whose courts can exercise universal jurisdiction to prosecute.
