A suspected Tunisian extremist accused of killing two Swedish soccer fans in a brazen shooting in Brussels has died of his injuries, ABC News has learned.

A car slammed into about 100 people, killing six, on Sunday morning during a carnival in Strépy-Bracquegnies, Belgium, officials said.

The man who killed two policewomen and a civilian in the Belgian city of Liege Tuesday morning is now believed to have killed a man the night before, authorities said.

Authorities are calling it a terror attack.

The suspect in Tuesday night's attempted bombing at a Brussels train station likely made the explosive at home, according to Belgium's federal prosecutor.

It is unclear if the suspect, who was neutralized, is dead or alive.

32 civilians died and at least 300 more were injured in the 2016 blasts.

Wednesday marked first anniversary of Belgium's deadliest terror attacks.

The Maelbeek subway station was the site of a terrorist bomb blast last month.

Richard Norby "has made positive strides in his recovery," the family said.

The terrorists instead turned their attention to Brussels.

One man was identified as one of the Brussels subway attackers.

Police in Brussels are working to confirm their involvement in the bombings.

Police say the third suspect from the airport bombing is on the run.

The Brussels airport is expected to restart flights on Sunday, 12 days after a deadly terrorist attack rocked one of the airport's departure halls.

Demonstrations were planned to protest Islamophobia and by right-wing groups.
