BRUSSELS—Belgian authorities said Tuesday they arrested two people on terrorism charges and broke up a plan for attacks during the holiday period, underlining fears of further mayhem in a Europe still unsettled over Islamic State’s deadly attacks in Paris last month.
Police seized Islamic State propaganda and military-style clothing but no explosives or arms in a series of raids Sunday and Monday in Brussels, Liège and the Flanders region of Belgium, prosecutors said.
The arrests were made amid stepped-up antiterrorism operations by Belgian authorities in the aftermath of the Nov. 13 Paris attacks, which were planned by a Belgian national and carried out by a team that included several others with ties to Belgium, including the fugitive Salah Abdeslam, a French citizen who was born and lived in Brussels.
