All of Brussels’ metro lines are back in operation after a manhunt for armed suspects in the tunnels of the city’s underground system brought public transport to a partial standstill.

The two metro lines and four tram lines that were partially suspended are gradually resuming their usual service, public transport company STIB-MIVB wrote on X platform on Wednesday.

Public broadcaster RTBF reported that two men carrying firearms were filmed by surveillance cameras inside a station in the district of Anderlecht shortly after shots were fired outside a station.

The suspects were believed to have fled into the underground tunnel system, news agency Belga quoted police spokeswomen Sarah Frederickx as saying.
