Manhunt after shooting at Brussels underground station

Belgian police have launched a manhunt after a shooting near an underground station in the capital.

Nobody was injured in the shooting, which happened outside Clemenceau metro station in Brussels at about 6am local time on Wednesday.

Clemenceau, Trone and Gare de l'Ouest underground stations were closed to the public while police searched for the perpetrators in the tunnels of the city's metro system, The Brussels Times reported.

CCTV footage showed two people walking into the station and opening fire, according to the Reuters news agency. It said it could not immediately verify the images.

"The suspects fled in the direction of the metro station and may still be in the tunnel between the Clemenceau and Midi stations," a police spokesperson told Belga News Agency.

"The Brussels Midi police and the federal railway police are searching the area. No one was injured in the shooting."

The suspects had aimed at a person but missed, Belgian broadcaster VRT reported.

Belgian prosecutors said the incident was not being considered a terror attack.

In a statement, the public prosecutor's office in Brussels said a forensics team was deployed to the scene of the shooting, including a ballistics expert.

"Several shell casings were found on site," it said.

"A major search operation was carried out, as video-surveillance footage showed two suspects fleeing into the metro tunnels."

It added: "No one has been arrested, but the investigation is continuing.

"At this stage, there is no indication of a terrorist motive for this shooting."

Images showed emergency services - including firearms officers, paramedics and firefighters - at the scene, and a police cordon in place.

Several tram and metro services have also been suspended on the heavily used public transport system.
