Amsterdam police chief Peter Holla stated at a press conference on Friday that the past 36 hours have shocked him.

“Supporters from Israel have experienced anxious moments, have been deliberately attacked and some have been outrageously abused,” he said in Dutch. “I would like to express my sympathy and support for the injured and all supporters who have felt or still feel unsafe. Protecting these people is our top priority, along with tracking down individuals who have been involved in the violent incidents.”
