Mediapart has published a video filmed in the summer of 1994 by French soldiers in Rwanda. It exposes the passivity of the army during one of the most embarrassing episodes for France during the genocide in that country: the massacre at Bisesero. The revelation comes as French judges complete their long investigation into the claims that the French military was "complicit" in genocide and crimes against humanity. Meanwhile human rights groups say they fear that the victims of the atrocities will be denied justice. Fabrice Arfi reports.
