Belgian police have arrested six people in Brussels as a major investigation continues into attacks that claimed 31 lives in the city on Tuesday.
The arrests were made in the Schaerbeek district. There is no word yet on the identities of the suspects or their possible connection to the attacks.
Separately, in France, a suspect who was plotting an attack has been arrested near Paris, officials said.
The Brussels bombings have been linked to last November's Paris attacks.
So-called Islamic State (IS) has claimed the attacks in both Paris and Brussels.
