Belgian authorities say they have detained a fifth suspect linked to an alleged terror cell plotting a major attack on police, while three others have been remanded in custody. The federal prosecutor’s office said the fifth suspect was apprehended in Brussels Tuesday. The three others were detained after a major anti-terror raid last week. They include a suspect who escaped alive from a firefight with police in eastern Verviers when two others were killed. Authorities claim they were part of a group only hours away from a major terror attack. Another person suspected of being linked with jihadi terrorists in Belgium was detained Sunday in Athens, Greece.
