War crimes in the Kosovo War in the context of "Armed Forces of Serbia and Montenegro"

The North Atlantic Treaty Organization (NATO) carried out an aerial bombing campaign against the Federal Republic of Yugoslavia during the Kosovo War. The air strikes lasted from 24 March 1999 to 10 June 1999. The bombings continued until an agreement was reached that led to the withdrawal of the Yugoslav Army from Kosovo, and the establishment of the United Nations Interim Administration Mission in Kosovo, a UN peacekeeping mission in Kosovo. The official NATO operation code name was Operation Allied Force (Serbian: Савезничка сила / Saveznička sila) whereas the United States called it Operation Noble Anvil (Serbian: Племенити наковањ / Plemeniti nakovanj); in Yugoslavia, the operation was incorrectly called Merciful Angel (Serbian: Милосрдни анђео / Milosrdni anđeo), possibly as a result of a misunderstanding or mistranslation.

NATO's intervention was prompted by Yugoslavia's bloodshed and ethnic cleansing of Kosovar Albanians, which drove the Albanians into neighbouring countries and had the potential to destabilize the region. Yugoslavia's actions had already provoked condemnation by international organisations and agencies such as the UN, NATO, and various INGOs. Yugoslavia's refusal to sign the Rambouillet Accords was initially offered as justification for NATO's use of force. Because Russia and China could use their veto within the Security Council to not authorize an external intervention, NATO launched its campaign without the UN's approval, stating that it was inter alia a humanitarian intervention. The UN Charter prohibits the use of force except in the case of a decision by the Security Council under Article 42, under Article 51 or under Article 53. Three days after the commencement of hostilities, on 26 March 1999, the Security Council rejected the demand of Russia, Belarus and India for the cessation of the use of force against Yugoslavia.
