Former Rwandan gendarme Philippe Hategekimana, naturalized French in 2005, is accused of genocide and crimes against humanity. Israel Dusingizimana is a key witness for the prosecution.

He was at the Nyanza gendarmerie when the captain asked "Biguma" to take weapons, including a mortar, to attack the Tutsi refugees on Nyabubare hill. At the end of the afternoon, the witness, diabetic, feels unwell and must be evacuated to the hospital.
