Two people have been arrested by Belgian authorities on suspicion of plotting terrorist attacks in “emblematic places” in Brussels on New Year’s Eve, Belgium’s federal prosecutor said.

The police anti-terrorist raid took place in Brussels, eastern Liège province and in Flemish-speaking Brabant, central Belgium, on Sunday and Monday.

The announcement did not say whether the suspects were male or female.

During the searches, the office says military-type training uniforms, propaganda materials from the militant group and computer material were seized and are being examined. However, no weapons or explosives were found.
