Two people were arrested in Belgium on Sunday and Monday, both suspected of plotting an attack in Brussels on New Year’s Eve, federal prosecutors said.
Police found military clothing and Islamic State propaganda material but no weapons or explosives, prosecutors said on Tuesday.
“Our investigation revealed serious threats of an attack on symbolic places in Brussels during the celebrations for New Year’s Eve,” the prosecutors said in a statement.
A total of six people had been taken in for questioning during house searches in Brussels, a neighboring province and Liege, but four of them had since been released, the prosecutors added.
