This article analyses the practice of international courts and tribunals regarding attacks against peacekeepers based on judgments of the International Criminal Tribunal for Rwanda, the Special Court Sierra Leone (SCSL) and the Pre-trial Chamber of the International Criminal Court (ICC). Directing attacks against personnel involved in peacekeeping missions, as long as they are entitled to the protection given to civilians or civilian objects under the international law of armed conflict, is defined as a specific war crime in the ICC Statute and was later incorporated into the Statute of the SCSL.
