A new terror investigation is underway in Paris after a failed attack exactly one year after the Charlie Hebdo newspaper massacre.

FOX's Simon Owen reports from the European bureau:

Armed with a knife and reportedly shouting, "God is great" in Arabic, a man shot dead by police as he attempted to enter a police station.

The French interior minister... Confirming it's being investigated by anti-terror authorities. Prosecutors say the man was carrying an image of the ISIS flag and was wearing what looked like a suicide vest. That turned out to be a fake.

Officials saying they don't believe anyone else is involved.
