Practice Relating to Rule 33. Personnel and Objects Involved in a Peacekeeping Mission
In 1991, in an appeal addressed to the President of the UN Security Council, the Ministry of Foreign Affairs of Ukraine stated:
Shooting at the UNPROFOR military personnel is a gross violation of the principles and norms of international law and may be considered by the Governments of States, contributing their military contingents to the United Nations peace-keeping forces, as hostile actions against their citizens. The Government of Ukraine strongly demands that the sides in conflict, in particular the Governments of Bosnia and Herzegovina, as well as of Serbia undertake all necessary steps for immediate and unconditional cessation of hostile actions against the United Nations peace-keeping forces, the Ukrainian battalion among them in the Sarajevo sector.
