A man has shot dead two police officers and a passerby in the Belgian city of Liege.
Authorities say he attacked two female police officers with a knife, inflicting multiple stab wounds. He then shot them dead with their own guns.
The attacker also shot dead a 22-year-old man in a nearby car.
He then entered a school where he took a woman working there hostage.
As he tried to leave the school he was shot and killed by police.
Belgium's national broadcaster RTBF identified the gunman as a 36-year-old from the town of Rochefort who was on day release from prison.
The incident is being investigated as a terrorist act.
