The Serbs, although initially militarily superior due to the weapons and resources provided by the JNA, eventually lost momentum as the Bosniaks and Croats allied themselves against the Republika Srpska in 1994 with the creation of the Federation of Bosnia and Herzegovina following the Washington agreement. Pakistan defied the UN's ban on supply of arms and airlifted missiles to the Bosnian Muslims, while after the Srebrenica and Markale massacres, NATO intervened in 1995 with Operation Deliberate Force targeting the positions of the Army of the Republika Srpska, which proved key in ending the war. The war was brought to an end after the signing of the General Framework Agreement for Peace in Bosnia and Herzegovina in Paris on 14 December 1995. Peace negotiations were held in Dayton, Ohio and were finalised on 21 November 1995.
