Belgian police detained at least three people with suspected links to Friday's terror attacks in Paris that left at least 129 people dead, as raids continued Saturday evening in Brussels.

Authorities held two Belgians suspected of taking part in the attacks as the terror probe continues, Interior Affairs Minister Jan Jambon said on VTM television. A third arrest was made in the capital district of Sint-Jans-Molenbeek, prosecutors said.

"Multiple arrests and search warrants have been executed," Eric Van Der Sypt, a spokesman for the Belgian federal prosecutors' office, told reporters. "These operations are still ongoing as we speak."

The raids followed French requests related to a Belgian-plated rental car found near the Bataclan concert hall, Belgium's Federal Prosecutor's office told reporters.

Brussels police arrested a man who rented a gray Volkswagen Polo found close to Bataclan, Minister of Justice Koen Geens said in interview with RTBF.

"The car was hired in Belgium and taken to Paris," Van Der Sypt said. Security forces across Europe are searching for clues about the perpetrators of the attacks at seven locations in the French capital Friday night and whether they had support.

Belgian Prime Minister Charles Michel said he will reconvene the committee analyzing terrorist-threat levels later on Saturday after the establishment of a Belgian link with the events in the French capital. Michel declined to respond to questions on the arrests. The nation initially left the threat level unchanged.
