Quoting an unidentified source, the IS-linked Amaq Agency said yesterday's attack came "in response to calls to target citizens" belonging to countries in a US-led coalition bombing IS in Syria and Iraq.
The assailant died yesterday after being shot by officers. Police said today he was a 33-year-old Algerian with the initials K B.
Belgium today opened a terrorism probe into the attack, the latest in a string of jihadist assaults in Europe.
Michel, who saluted the courage of the police victims, was referring to the attacker's cry of "Allahu Akbar" (God is greatest) during the assault in front of a police station.
Police spokesman David Quinaux told broadcaster RTL-TVI the assailant had "taken a machete out of a sports bag he was carrying and dealt very violent blows to the faces of the two policewomen".
Belgium has been on high alert since suicide bombers struck Brussels airport and a metro station near the European Union's institutions on March 22, killing 32 people.
