Police in Belgium say they have detained five people for questioning in an investigation linked to militant attacks in Paris that killed 130 people in November.
Police detained two brothers and their friends in a raid on a central district of Brussels late on December 20. Two more people were taken into custody in another search on December 21 in the north of the city.
Following the November 13 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.
