and Herzegovina In contrast to that of Croatia, the UNPROFOR mandate for Bosnia and Herzegovina was not to monitor a preexisting cease-fire. The mandate can essentially be divided into four phases: Phase 1: Aid to Sarajevo - Beginning on 5 June 1992, UNPROFOR was responsible for the protection of Sarajevo airport as mandated by Resolution 758 for humanitarian purposes. UNPROFOR would run a security corridor for aid convoys between the airport and the city. Phase 2: Escort of Humanitarian Aid - On 14 September 1992, UNPROFOR was given a mandate (United Nations Security Council Resolution 776) by the United Nations Security Council to provide protection to humanitarian organisations such as the International Committee of the Red Cross, and other activities as requested by the United Nations High Commissioner for Refugees such as scheduling convoys and negotiating safe passage. The Force would also be permitted to use self-defence if armed persons attempted to prevent it from carrying out its mandate. Phase 3: The Protection of Safe Areas - The next expansion of the mandate was on 16 April 1993 with United Nations Security Council Resolution 819 declaring the town of Srebrenica a "safe area" free "from armed attack or any other hostile act." In May 1993, Bihać, Sarajevo, Goražde, Žepa and Tuzla were also added as "safe areas". Phase 4: Monitoring the Muslim-Croat Federation and Weapons Exclusion Zones - Eventually, UNPROFOR monitored a US-brokered cease-fires in Bosnia in February 1994, creating the Muslim-Croat Federation. UNPROFOR was responsible for monitoring the zones of separation and weapons control points. In addition, the UNSC increased UNPROFOR's authorized strength to monitor weapons exclusion zones, but never actually altered the operation's mandate. On 31 March 1995, UNPROFOR was restructured into three coordinated peace operations. On 20 December 1995, the forces of UNPROFOR were reflagged under the NATO-led Implementation Force (IFOR), whose task was to implement the General Framework Agreement for Peace in Bosnia and Herzegovina (GFAP – otherwise known as the Dayton Accords or Dayton Agreement). Course of action February 1992 – March 1993 Cedric Thornberry was director of UNPROFOR Civil Affairs at the beginning of the mission in February 1992. By the end of its first mandate in March 1993, UNPROFOR had some success in restoring peace in Croatia, notably obtaining the removal of the Yugoslav People's Army (JNA) in May 1992. However, civil unrest was such that terror, discrimination and "ethnic cleansing" were still
