A MANHUNT is underway in Belgium after several armed men were spotted on the metro in Brussels.

Police officers are searching for a group of men after shots were fired at 6:15 am local time in front of the Clémenceau station in Anderlecht, the west part of the city.

CCTV footage obtained by RTBF showed two heavily hooded men wearing balaclavas armed with what appear to be Kalashnikovs at the entrance and inside the station.

Brussels Police have said they are looking for “a small group of people, probably two or three individuals.”

Footage taken from a building outside the station whose two men calmly walking around the entrance with their weapons as commuters walk by.

They then started firing at an unknown target out of shot causing bystanders to flee into the station.

One hangs back as a man in a grey hoodie runs forward while firing before the pair sprint into the station and through the barriers.

Brussels Police have confirmed that no one was injured.

Officials are continuing to hunt for the suspects who are believed to have fled into the underground tunnels towards the South Station Metro Station.

Searches are underway in the metro tunnels between the Trône and Gare de l’Ouest stations, bringing many transport links to a halt.

At 6:30 local time, services metro traffic on lines 2 and 6 were stopped and the Constitution” tunnel near the Gare du Midi has also been closed.

Brussels-Midi station which is also the terminal for Eurostar trains has also been closed.

Officials have warned that searches for the men could go on for a number of hours.

Local reports state that the incident is believed to be related to drug trafficking.

Sarah Frederickx, spokeswoman for Brussels Police said that both local and federal railway police are taking part in the search.

The spokeswoman added that investigators would have to proceed with caution due to the weapons believed to still be in the suspects’ possession.

She said: “They are possibly still armed, and we don’t want to take any unnecessary risks.

“We understand that this is a far-reaching measure taken at a difficult time of the day.

“We will reopen the tunnels as quickly as possible.”

Thousands of commuters have been impacted by the incident with the city’s public transport company MIVB warning chaos could continue for a long time.

A spokesperson said: “South Station is the busiest station on the network and there are also a lot of commuters that arrive there by train and take the metro there.

“As a result of this the impact is major. We don’t know how long it will go on for.”
