BRUSSELS — A man detonated a bomb in the Brussels Central train station on Tuesday, officials said, leading the police and military to evacuate a popular tourist area of the Belgian capital months after coordinated terrorist attacks in the city killed more than 30 people.

“There was a person who set off a bomb,” Jean-Michel Michel, who was managing the station at the time of the explosion, said in an interview.

A platform worker at the station said that before the blast, he heard a man shout “Allahu akbar” (Arabic for “God is great”) and saw him try to enter an office with a rolling suitcase before detonating the device at another location.

The platform worker, Nicolas Van Herrewegen, said he did not see what happened to the man after the explosion, but a spokesman for Belgium’s federal prosecutor later told reporters that the man had been shot by soldiers patrolling the station.
