MADRID (AP) — Victims of terror attacks are a symbol of the constant need to guard freedom and the rule of law against threats, King Felipe VI of Spain said Monday at a ceremony marking the 20th anniversary of one of Europe’s deadliest extremist attacks.

“Remembering, just like justice and truth, is a commitment that cities make to terror victims, to restore and protect their dignity,” Felipe told officials attending the European Remembrance Day for Victims of Terrorism.
