France says it has arrested a person suspected of planning an attack against marines at a naval base in the southeastern French city of Toulon.

French Interior Minister Bernard Cazeneuve released a statement Tuesday that said the "radicalized" person was arrested on Oct. 29 and is now in police custody.

He said the person had publicly supported jihadi views and had been under surveillance.

Cazeneuve said that the suspect had sought out material to carry out a planned attack, but didn't give any more details.
