An explosion rocked the central train station in Brussels on Tuesday and a man was shot dead by police during the incident, prosecutors told the media.

A suspect shouted out "Allahu Akbar" (God is Greatest) before causing the explosion, a witness said.

Prosecutors told AFP the suspect died from his injuries, and Belgium's national crisis centre said the situation was under control.

The incident took place around 1900 GMT, causing the city's Gare Centrale to be evacuated. The nearby Grand Place, a major tourist destination, was also evacuated.
