Context: Ljubiša “Mauzer” Savić (Serbian: Љубиша Маузер Савић ; 11 August 1958 – 7 June 2000) was a Bosnian Serb war-time paramilitary commander and post-war politician.  He led the "Panteri" brigade during the Bosnian War of 1992-1996.  His actions in the war included the securing of Bijeljina to Republika Srpska forces as well as the liberation of the sieges of villages Smoluća and Tinja.  Many of his actions during the war were made into songs featured in the album "Garda Panteri" by Rodoljub "Roki" Vulovic, a Bosnian Serb turbo-folk singer and former soldier of Garda Panteri. Sakib Mahmuljin (born 13 October 1952 ) is a former Bosnian Army (ARBiH) brigadier general and deputy minister of defense in FBiH, a senior official of the Party of Democratic Action (SDA).  He was born in Kozarac.  During the Bosnian War (1992–95) he was a top Bosnian Muslim general and the commander of most units of Bosnian mujahideen, whom he advocated for and protected.  Mahmuljin is recorded on video meeting with mujahideen leaders.  He became the commander of the 3rd Corps in September 1994.  He has stated that the mujahideen sent 28 severed heads of POW Bosnian Serb soldiers to Bosnian President Alija Izetbegović and Iran.  His two brothers Omer and Nagib were killed at the Omarska camp.  After the Dayton Agreement (September 1995), he arranged for the settlement of 89 mujahideen families in Bočinja (Gornja and Donja).  Dževad Galijašević, the mayor of Maglaj municipality in 2000, ordered for the removal of the mujahideen occupying Serb homes in Bočinja, but the order was never carried out.  After the war he became the Vice-Minister of Defense.  On 7 October 1999 he travelled with the Bosnian defense delegation to Pakistan to discuss further strengthening of relations. Franz Ferdinand Carl Ludwig Joseph Maria (18 December 1863 – 28 June 1914) was an Archduke of Austria-Este, Austro-Hungarian and Royal Prince of Hungary and of Bohemia and, from 1896 until his death, heir presumptive to the Austro-Hungarian throne. The Batković camp (Bosnian, Croatian and Serbian Latin: "Logor Batković") was a concentration camp operated between 1992 and 1996 by Bosnian Serb authorities in Batković, a village in the municipality of Bijeljina, Bosnia and Herzegovina during the Bosnian War.  It is believed to have been the first concentration camp of the Bosnian war, set up for Bosniak (Muslim) and Croat men, women and children, in an effort to ethnically cleanse the areas under Bosnian Serb control.  Detainees were held in two large barns and tortured, deprived of food and water, forced to dig trenches, carry ammunition to the front lines, work in fields and factories and bury the dead.  Prisoners were subject to daily beatings, sexual assault and forced to beat one another. Zdravko Tolimir (Serbian Cyrillic: Здравко Толимир; 27 November 1948 – 9 February 2016) was a Bosnian Serb military commander and war criminal, convicted of genocide, conspiracy to commit genocide, extermination, murder, persecution on ethnic grounds and forced transfer.  Tolimir was a commander of the Army of Republika Srpska during the Bosnian War.  He was Assistant Commander of Intelligence and Security for the Bosnian Serb army and reported directly to the commander, General Ratko Mladić. Drago Nikolić (Serbian Cyrillic: Драго Николић; 1957–2015) was a Bosnian Serb who participated in the War in Bosnia and Herzegovina.  He was the 2nd Lieutenant who served as Chief of Security for the Zvornik Brigade of the Bosnian Serb Army. Operation "Deliberate Force" was a sustained air campaign conducted by the North Atlantic Treaty Organisation (NATO), in concert with the United Nations Protection Force (UNPROFOR) ground operations, to undermine the military capability of the Bosnian Serb Army (VRS), which had threatened and attacked UN-designated "safe areas" in Bosnia and Herzegovina during the Bosnian War with the Srebrenica and Markale massacres, precipitating the intervention.  The operation was carried out between 30 August and 20 September 1995, involving 400 aircraft and 5,000 personnel from 15 nations.  Commanded by Admiral Leighton W. Smith, the campaign struck 338 Bosnian Serb targets, many of which were destroyed.  Overall, 1,026 bombs were dropped during the operation, 708 of which were precision-guided. Momčilo Krajišnik (Serbian Cyrillic: ; born 20 January 1945) is a former Bosnian Serb political leader, who along with Radovan Karadžić co-founded the Bosnian Serb nationalist Serb Democratic Party (SDS).  Between 1990-92, he was Speaker of the People's Assembly of Republika Srpska.  Between June and December 1992, he also served as member of the expanded Presidency of Republika Srpska. During the Bosnian War, there was an ethnic cleansing campaign committed by the Bosnian Serb political and military leadership mostly against Bosniak civilians in the Prijedor region of Bosnia and Herzegovina.  After the Srebrenica genocide, it is the second largest massacre committed during the Bosnian War.  According to the Sarajevo-based Research and Documentation Center (IDC), around 5,200 Bosniaks and Croats from Prijedor are missing or were killed during the massacre period, and around 14,000 people in the wider region of Prijedor (Pounje).  s of October 2013 , 96 mass graves have been located and around 2,100 victims have been identified, largely by DNA analysis.  The crimes committed in Prijedor have been subjected to 13 trials before the International Criminal Tribunal for the Former Yugoslavia.  Soldiers and police in the Serb SDS, Crisis Staff's, including Milomir Stakic, Milan Kovacevic, Radoslav Brdanin, ranging to the highest leaders including General Ratko Mladic, Bosnian Serb President Radovan Karadzic, and Serbian President Slobodan Milosevic have been charged with genocide, and persecution's, extermination's, murder, forced transfers, and unlawful confinement, torture as Crimes Against Humanity (widespread, systematic attacks against a civilian population) and other crimes, have been alleged to have occurred in Prijedor.  The ICTY has characterized the Prijedor events of 1992 as having met the "actus reus" (guilty act) of genocide through killing members of the group and causing serious bodily and mental harm to members of the group.  However, the requirement of the specific intent to physically destroy having failed to be established beyond reasonable doubt.  However the events of 1992 in Prijedor were part of the larger Joint Criminal Enterprise to forcibly remove Bosnian Muslims and Croats from large territories of Bosnia.  In 2014, investigators were led by two Bosnian Serb civilians who worked in and around the camps to a mass grave at the Tomasica mining complex, unearthing the largest mass grave in Bosnia, and the discovery of over 1,000 bodies in both the Tomasica and Jakarina Rose mass grave sites.
