BRUSSELS — Belgian police are searching for armed gunmen following a shooting outside a metro station in Brussels on Wednesday morning.

Two metro lines and multiple trams in the Belgian capital were disrupted as police hunted for the culprits.

Footage shown on local media showed at least two men wearing balaclavas and carrying weapons exchanging fire outside Clémenceau station in the Belgian capital at around 6 am CET.

A spokesperson for the public prosecutor's office told Euronews the police were actively searching the underground network, and there were no injuries in the incident.

Police spokesperson Sarah Frederickx told the domestic press the suspects may still be in the tunnel between the Clémenceau and Midi stations and that both Brussels Midi police and the federal railway police were searching the area.

Frederickx added that they were looking for a small group of maybe "two or three individuals" who were likely still armed.

The incident is not being considered a terrorist attack, according to the city's public transport operator.

Clemenceau and Delacroix stations have been closed, as well as the central Gare du Midi, which serves as a terminal for Eurostar trains.

Local media reports suggested the incident was connected to drug trafficking, with local outlets alleging the suspects were carrying Kalashnikov rifles.

Metro lines 2 and 6 were interrupted between the stations Trône and Gare de l'Ouest, near the European Parliament.

Tramlines between stations Lemonnier and Berkendael and between Port d'Anderlecht and Gare du Midi stations were also disrupted.

The disruption, which occurred during the city's regular early morning rush hour, impacted thousands of commuters. — Euronews
