The assailant who attacked two policewomen in Belgium with a machete was identified by a prosecutor Sunday as a 33-year-old Algerian with a criminal record but no known connection to terrorism.
The man, who wounded two officers in the southern city of Charleroi, was named only as as "K.B."
A Belgian prosecutor said he has lived in Belgium since 2012.
The assault at a security checkpoint outside of a police precinct left the two officers "severely injured" in the face and neck, according to the Belgian prosecutor. A third officer then fired shots at the suspect, who was hospitalized and later died.
K.B. was "known to police" for criminal acts, "not for terrorism," the prosecutor said, without going into detail on the man's record.
But the ISIS-affiliated Amaq Agency on Sunday claimed responsibility for the attack, according to global security firm and NBC News consultant Flashpoint Intelligence.
Belgian Prime Minister Charles Michel said Saturday that "preliminary indications" suggest the assault was linked to terrorism, but said the motive was still under investigation.
ISIS has a history of claiming responsibility for attacks by people who are not directly affiliated with the terror group but just motivated or inspired by them.
According to reports, the suspect yelled "Allahu Akbar" ("God Is Great") during the rampage.
A bag that the suspect was carrying was examined, but no traces of explosives were found. Two homes were also searched in connection with the investigation, the prosecutor said, without disclosing additional information.
Belgian Interior Minister Jan Jambon said Saturday that it wasn't immediately clear if the suspect acted alone.
Prime Minister Charles Michel said Sunday that security would be ramped up at police stations in Belgium.
On Sunday, Charleroi police posted a request on their Twitter account asking reporters not to divulge officers' identities.
"We are targets," Charleroi police explained.
Belgium has been on high alert since the March 22 suicide bombings claimed by ISIS extremists that killed 32 people in Brussels. Many of the perpetrators of the Nov. 13 carnage in Paris that killed 130 people were also residents of Belgium.
