Belgian arrested two suspects and issued arrest warrants against three others following anti-terror raids Monday.
Police said earlier that they simultaneously raided 21 locations as part of two probes into jihadist Chechen groups, the country’s federal prosecutors’ office said in a statement. Prosecutors said the arrests were based on police information concerning a wounded man who had returned to Belgium after taking part in the jihad in Syria.
Authorities said they had to let go four other people detained earlier on Monday as part of a separate probe into the participation of a Chechen group based in the Belgian city of Leuven in the preparation of a possible terrorist attack in the country.
European law enforcement agencies have grappled with the threat of a domestic terrorism as extremist groups have encouraged followers to carry out attacks on home soil rather than try to travel to the Middle East. Two suspected terrorists were killed in January in a shootout that Belgian police said foiled a possible “major” attack.
Investigators said earlier they had detained 16 people in the anti-terror raids after working with U.S. authorities to monitor suspects’ communications on WhatsApp Inc.’s messaging service.
