Belgian authorities question two Israelis accused of war crimes in Gaza.

MADRID (EUROPA PRESS) - The Belgian Prosecutor's Office announced Monday that two Israelis who were at the Tomorrowland electronic music festival have been questioned after being accused of committing war crimes in the Gaza Strip, although authorities later released them.

The interrogation took place after several NGOs—Hind Rajab Foundation and the Global Legal Action Network—filed two complaints about the presence at the festival of two men allegedly part of an Israeli army brigade who waved their unit's flag during the musical event.

The plaintiffs accused the two Israelis of war crimes and genocide in Gaza, claiming they were "directly" involved in deliberate attacks on civilian areas, the use of torture, and the forced displacement of civilians. They also consider the waving of their brigade's flag a symbol of impunity.

After reviewing the complaints, the Public Prosecutor's Office concluded that it could have jurisdiction to investigate crimes committed outside of Belgium and covered by international law. Therefore, it requested that the police locate the two defendants. At this stage of the investigation, it has concluded that it will not provide further information.

In an initial response, the Hind Rajab Foundation called the interrogation of the two Israeli soldiers "historic" and maintained that it "could become a turning point in the global search for justice."

"At a time when too many governments remain silent, this action sends a clear message: credible evidence of international crimes must be met with a legal response, not political indifference," read a statement posted on its website.

The foundation acknowledged that justice has not been done "yet," but believes that "something important has begun," given that "for the first time in Europe, Israeli suspects linked to crimes in Gaza have been subjected to arrest and formal interrogation."
