Bosnia and Herzegovina commemorates the 30th anniversary of the Srebrenica genocide, a horrific event in which thousands of Bosnian Muslim men and boys were systematically murdered. Al Jazeera's Alma Milisic provides a detailed account of the events leading up to, during, and after the massacre. The commemoration serves as a solemn reminder of the devastating consequences of ethnic hatred and the importance of preventing future atrocities. The international community continues to grapple with the legacy of Srebrenica and the failures that allowed the genocide to occur.
