Belgian and French police launched together a huge manhunt for two suspects in Brussels after gunmen opened fire wounding four officers, during an anti-terror operation linked to the Paris attacks.

On Tuesday evening the Belgian prosecutor’s office said that “as part of the investigation being carried out following the Paris attacks, a raid was carried out this afternoon, around 3pm, on an apartment on Rue du Dries in Forest.” as Financial Times reports.

“Four policemen were wounded: three immediately, including a French officer, and a fourth later during exchanges of gunfire”, Belgian prosecutor’s office said.

“A suspect armed with a Kalashnikov-style firearm was killed during the assault, around 18.15 (17.15 GMT). The process of identifying them is under way.”

Salah Abdeslam, a key suspect in the November Paris attack which killed 130 people and who fled to Brussels after the attacks, was not the target of the Brussels search, sources said.

Following the raid in the apartment, heavily armed police launched a manhunt while an helicopter was flying over the area searching for the suspects.
