Belgium's crisis center is keeping the security alert status at its current level despite reports that fighters from Syria could pose an imminent threat.

Crisis center spokesman Benoit Ramacker said Wednesday that "we are still on level three, quite a high level of threat."

Level three out of a possible four means the threat is considered serious, possible and probable.

The Derniere Heure tabloid reports Belgium's anti-terror office has warned police that fighters with access to weapons could have left Syria about 10 days ago bound for Belgium and France.

The paper said a Brussels shopping mall, an American fast-food chain and police were reported to be among their targets.

Ramacker said "these kinds of potential targets are under protection anyway" and that "nothing has changed in terms of security."
