The interior minister says police have arrested six people in northeastern France in a roundup of suspected jihadists who traveled to fight in Syria's civil war.

The sweep around dawn Tuesday in Strasbourg comes weeks after authorities announced a new push to stop French militants from traveling to Syria.

Interior Minister Bernard Cazeneuve said the six were suspected of participating in a jihadist network, and recently traveled to Syria.

Hundreds of young French militants have traveled to Syria. Authorities fear they could return home with fighting skills.
