Hundreds of protesters have marched in Serbia against last week's acquittal of a Hungarian suspect in a World War II massacre of Serbs and Jews.

The court in Budapest freed 97-year-old Sandor Kepiro because of what it said was a lack of evidence.

At Sunday's marches in Belgrade and Novi Sad, where the massacre took place, organizers called it the “He's Guilty” rally. They condemned the Hungarian court decision as a disgrace.

Kepiro was accused of being a member of the pro-Nazi Hungarian police in World War II, when Hungary took over parts of Serbia.

He allegedly took part in a massacre of as many as 2,000 Serbs, Jews and others in January 1942, and throwing some of the bodies into the icy Danube River.
