Belgian investigators on Wednesday said an Islamic State-style attack that killed three people in the eastern city of Liege was being treated as an act of terrorism.
The bloodshed shocked the eastern industrial city of Liege on Tuesday when the attacker armed with a knife repeatedly stabbed two policewomen before using their own firearms to kill them, a method investigators said was encouraged in online videos by the Islamic State extremist group.
Police were scrambling to unpick the motives of the attacker identified as Benjamin Herman, a 31-year-old drifter with a decade spent in and out of prison for acts of violence and petty crimes, who was out of jail on leave when he attacked.
“The facts are qualified as terrorist murder and attempted terrorist murder,” prosecutors’ spokesman Eric Van Der Sypt told a news briefing in Brussels.
Van Der Sypt said the assessment was based on several “first elements” from the probe, including “the fact the perpetrator shouted several times shouted ‘Allahu akbar’ … and information from state security according to which the perpetrator was in touch with radicalised persons.”
But he cautioned that the information dated “from late 2016, early 2017” and had not been confirmed since.
Prosecutors also underlined that the attacker’s method — attacking armed police officers and using their weapon against them — was a known “modus operandi” of the IS terror group, which claimed deadly attacks in Brussels in 2016.
Amateur footage obtained by AFP showed the gunman shouting “Allahu akbar” (Arabic for “God is greatest”) as he walked through the Liege streets during the rampage.
In another video, the suspect darts out of a school where he had holed up into a short and intense burst of police gunfire, after which the man collapses to the ground.
But Interior Minister Jan Jambon urged caution over the extremist angle.
“There are signals that there was radicalisation in the prison but did this radicalisation lead to these actions? There too we can ask ourselves a lot of questions,” he told RTL radio.
