Following searches, two men have been arrested in Belgium on suspicion of planning terror attacks in the Belgian capital during the holidays, the federal prosecutor’s office announced.

Military-type training uniforms, propaganda materials from Islamic State and computer material were seized. However, no weapons or explosives were found.

The investigation revealed “the threat of serious attacks that would target several -emblematic places in Brussels and be committed during the end-of-year holidays.”

The men are suspected to have discussed attacking Brussels' Grand Place square and other places where crowds gather as well as police and military facilities.

One of the two was charged with ¬acting as the leader and ¬recruiter of a terrorist group planning to commit terrorist offences, the other with participating in a terrorist group’s ¬activities as a principal actor or co-actor.

The prosecutor’s office said the probe was not connected to the November 13 terror attacks in Paris, in which presumed ringleader Abdelhamid Abaaoud and fugitive Salah Abdeslam, were coming from Belgium.
