Islamic State claimed responsibility on Wednesday for an attack the previous day in the Belgian city of Liege in which two policewomen and a bystander were killed, but provided no proof.
The militant group said in an online statement that a “soldier of the caliphate” had carried out what Belgian police called a terrorist attack. It has previously claimed similar “lone wolf” acts thought to be Islamist-inspired, often without providing evidence.
Belgian authorities meanwhile faced questions over why the attacker, a prison inmate who was suspected of links to radical Islamists in jail, was let out for a day. He was shot dead by police at a school near the scene.
