Two people have been arrested in Belgium on suspicion of planning attacks in Brussels during the holidays, the federal prosecutor's office said Tuesday, according to AP. The two were arrested following searches Sunday and Monday in the Brussels area, the Liege region and Flemish Brabant, the office said. The announcement did not say whether the suspects were male or female. During the searches, military-type training uniforms, propaganda materials from the ISIS group and computer material were seized and are being examined. However, no weapons or explosives were found, the prosecutor's office said. A total of six people were taken in for questioning. Four were released, but two were placed under arrest on charges including participation in the activities of a terrorist group as a leader or recruiter with the aim of committing terrorist offenses as principal or secondary actor, the prosecutor's office said.
