Belgian security forces are hunting for at least two men after shots were fired at police during a counter-terrorism raid in the capital, Brussels.
The incident took place in the southern suburb of Forest. Three officers were reportedly hurt, one of them severely.
A prosecutor said the raid was linked to the Paris attacks which killed 130 people last November.
Belgian police have been trying to track down militants from the self-styled Islamic State.
After Tuesday’s incident, police said they were pursuing at least two suspects who escaped over rooftops.
Eric Van Der Sypt, a spokesman for the federal prosecutor, told AFP news agency that “police were fired at” during the raid on Tuesday afternoon. He added that the raid was “linked to the Paris attacks investigation”.
A major police operation is now under way, with streets sealed off and a helicopter flying overhead.
