Belgium's justice minister says a French policewoman is among 4 officers "lightly wounded" in an anti-terror raid in Brussels earlier.
One suspect is also understood to have been shot dead in the operation that is linked to the Paris terror attacks in November.
A manhunt is ongoing in the Belgian capital.
Armed officers have told residents in an area to the south of the city to stay indoors.
The area where the raid operation took place in the Forest neighbourhood has been sealed off, and residents are being told to say indoors.
