Four men went on trial in Denmark Thursday accused of helping the gunman behind twin attacks on a Copenhagen synagogue and a free speech event last year that left two people dead.
The trial, being held under heavy security, comes with Europe still on high alert over fears of extremist violence following two bloody attacks in Paris in 2015.
Prosecutor Bo Bjerregaard accused the four defendants of trying to “destabilize or destroy Denmark’s basic political, constitutional, economic or societal structures”.
