Authorities in Belgium say jihadi items were found after a police shootout in Brussels on Tuesday.
The country’s prosecutor said the gunman killed during the operation was an Algerian known to police for a previous theft offence.
Anti-terror police arrived at a flat for a routine search. They came under fire from inside the building.
Prosecutors told reporters Mohamed Belkaid was shot dead when he tried to fire at the officers from a window. They said he had been living “illegally” in Belgium.
