At least three Belgian police officers have been injured in a shootout during a counterterrorism raid on a house in southern Brussels, according to a police spokesperson.
One of two suspected shooters was "neutralised" during manhunt after Tuesday's incident in the neighbourhood of Forest, the Belga news agency reported.
It was not clear whether the second suspect was still on the run.
Al Jazeera's Jacky Rowland, reporting from Paris, said: "Two suspects have escaped over the rooftops, according to eyewitnesses. Three police officers were injured in that exchange of fire.
"One of them was shot in the head and is seriously wounded."
The area - located near a factory of German car manufacturer Audi - has been secured by the police, according to media reports.
The raid was related to last year's deadly attacks in the French capital, Paris.

The November 13 attacks in Paris had left 130 people dead and hundreds injured, after armed men and suicide bombers targeted the Stade de France stadium, the Bataclan concert hall, cafes and bars.
Several of the suspected attackers had links to neighbouring Belgium.
The Forest neighbourhood is close to Molenbeek, home to several people involved in the Paris attacks.
The suspected ringleader of the attacks was a Brussels resident, Abdelhamid Abaaoud.
Another attacker, Bilal Hadfi, was said to have lived for a time in the Forest neighbourhood.
