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.
It follows a series of raids overnight, which led to six arrests, following the deadly attacks in the Belgium capital on Tuesday.
It's now thought up to ten people, including three in Germany, and one in France have been arrested.
Earlier the US Secretary of State and the Belgian Prime Minister Charles Michel held a joint press conference: Meanwhile Islamic State's second-in-command has reportedly been killed in a raid in Syria.
US media say the commander - who goes by several names - died yesterday in American led attacks.
