Jajinci is an urban neighborhood located in the municipality of Voždovac, in Belgrade, the capital of Serbia. It was the site of the worst carnage in Serbia during World War II when German occupational forces executed nearly 80,000 people, many of them prisoners of the nearby Banjica concentration camp. Jewish women and children from German Sajmište concentration camp, killed in a special gas truck on their way to Belgrade were also buried here.
