The HV and the special police suffered 174–211 killed or missing, while the ARSK had 560 soldiers killed. Four UN peacekeepers were also killed. The HV captured 4,000 prisoners of war. The number of Serb civilian deaths is disputed—Croatia claims that 214 were killed, while Serbian sources cite 1,192 civilians killed or missing. During and after the offensive, around 150,000–200,000 Serbs of the area formerly held by the ARSK had fled and a variety of crimes were committed against the remaining civilians there by Croatian forces. The International Criminal Tribunal for the Former Yugoslavia (ICTY) later tried three Croatian generals charged with war crimes and partaking in a joint criminal enterprise designed to force the Serb population out of Croatia, although all three were ultimately acquitted and the tribunal refuted charges of a criminal enterprise. The ICTY concluded that Operation Storm was not aimed at ethnic persecution, as civilians had not been deliberately targeted. The ICTY stated that Croatian Army and Special Police committed a large number of crimes against the Serb population after the artillery assault, but that the state and military leadership was not responsible for their creation and organizing. Croatia also adopted discriminatory measures to prevent the return of Serbs. Human Rights Watch reported that the vast majority of the abuses during the operation were committed by Croatian forces and that the abuses continued on a large scale for months afterward, which included executions of civilians and destruction of Serb property. In 2010, Serbia sued Croatia before the International Court of Justice (ICJ), claiming that the offensive constituted a genocide. In 2015, the court ruled that the offensive was not genocidal and that although the Serb population fled as a result, Croatia did not have the specific intent of displacing the country's Serb minority and that ethnic cleansing or civilian targeting did not occur. However, it was found that crimes against civilians had been committed by Croatian forces. , the Croatian judiciary has convicted 2,380 persons for various crimes committed during Operation Storm.
