Belgian police raided homes in Brussels late on Sunday and detained two people for questioning in an investigation linked to militant attacks in Paris that killed 130 people in November, federal prosecutors said.
The two, who were arrested near the trendy Dansaert neighbourhood in central Brussels, will go before a judge on Monday to determine whether they can be held further, Belgian prosecutors said.
Prosecutors did not specify what the two were suspected of but noted that the raids were carried out in connection with the Paris attacks.
Following the attacks in Paris, the focus of the investigation turned to Belgium, where several people suspected of having aided the attackers have been arrested.
Fugitive Brussels native Salah Abdeslam, who is suspected of direct involvement in the Paris attacks, is still at large.
