Belgian prosecutors have confirmed the link between the Paris attacks and one of the suspects from Tuesday's attack.
A major anti-terror raid has been conducted across the Belgian capital this afternoon.
A number of explosions have been reported while it's understood one person has been detained in police raids in the Brussels neighbourhood of Schaerbeek.
From Brussels, Newstalk.com's Shona Murray reports that in the last 24 hours, European police forces in three countries have arrested 11 people in terror raids.
Reports from Schaerbeek's Place Meiser in Brussels indicate that a suspect was shot before his arrest.
In addition, the Belgian prosecutor has now confirmed Najim Laachraoui as the second suicide attacker at the Brussels airport bombing.
The prosecutor's office has also confirmed that DNA traces from Najim Laachraoui were found on devices used in the Bataclan and Stade de France attacks.
