The International Criminal Court has begun hearing the trial of a former senior rebel commander in the Central African Republic.
Mahamat Said Abdel Kani has pleaded not guilty to charges of war crimes and crimes against humanity.
He is accused of being in charge of a police compound in the capital Bangui in 2013, where supporters of the deposed President François Bozizé were brutally tortured.
The trial is expected to last several months and the prosecutor will rely on the evidence of 43 witnesses.
Mr Said’s defence team dispute the reliability of the evidence against him.
