Belgian federal police have arrested two Israeli soldiers facing accusations of war crimes in Gaza following a complaint by two rights groups, Middle East Eye reports.

The complaint was filed last week by the Hind Rajab Foundation (HRF) and Global Legal Action Network (GLAN).

A statement by the HRF said the pair were in the country to attend a music festival and that legal proceedings were ongoing. “The suspects were identified and arrested with a clear show of force at the Tomorrowland festival in Boom,” it said.

“After being taken into custody, they were formally interrogated and released. The Belgian Federal Prosecutor’s Office has confirmed that a criminal investigation is now underway.”
