Belgian soldiers have shot a man suspected of being a would-be suicide bomber at Brussels Central Station, officials say.
He was shot after reportedly setting off a small explosion and no-one else is believed to have been injured.
Prosecutors later said the man had died. They are treating the incident as a terrorist attack.
In March 2016, 32 people were killed in attacks on Brussels claimed by the Islamic State (IS) group.
According to Belgian newspaper La Libre Belgique, quoting prosecutors, the man who was shot was wearing a rucksack and a bomb belt.

He detonated a device when he attracted the attention of soldiers in the station, the paper says.

Nicolas Van Herrewegen, a railway sorting agent, said he had gone down to the station's mezzanine level when he heard someone shouting.
"Then he cried 'Allahu Akbar' and he blew up a wheeled suitcase," he told AFP news agency.
"I was behind a wall when it exploded. I went down and alerted my colleagues to evacuate everyone. He [the suspect] was still around but after that we didn't see him."
"It wasn't exactly a big explosion but the impact was pretty big," he added. "People were running away."

Mr Van Herrewegen described the suspect as well-built and tanned with short hair, wearing a white shirt and jeans.
"I saw that he had something on him because I could see wires emerging, so it may have been a suicide vest," he said.
'Shutters down'
Arash Aazami arrived at the station just after the explosion. He told the BBC: "As we entered into the station, we were evacuated loudly by some security personnel.
"Looked around, saw people running in the streets, trying to seek refuge and decided to do the same ourselves."

As the station and Grand Place were evacuated, businesses and restaurants were ordered to close and draw down their shutters, RTL radio reports.
Metro lines running through the station were also briefly suspended on orders of the police, according to the radio.
On 22 March of last year, three suicide bombers mounted twin attacks on the city's Zaventem airport and Maelbeek underground station.
The same Brussels-based IS cell was also behind the gun and bomb attacks in Paris in November 2015, that killed 130 people.
The French capital was jolted again on Monday when a man with an Islamist background died after ramming his car into a police van on the Avenue des Champs-Élysée.
London has also been on edge since a van was driven into Muslim worshippers outside a mosque on Sunday night, with one man dying and nine people injured. It followed IS-claimed attacks on London's Borough Market in June and a pop concert in Manchester in May that together left some 30 people dead and more than 100 injured.
