BATON ROUGE — A fire broke out at L'Auberge Casino and Hotel early Monday morning. 

The fire was first reported at 1 a.m. as a structure fire, but a spokesperson for the St. George Fire Department told WBRZ the fire happened inside one of L'Auberge's restaurants. 

No firefighters were injured in the fire, but EMS transported four people from L'Auberge around the same time firefighters responded. The spokesperson said it's unclear if the injuries were related to the fire.

The cause of the fire is under investigation, officials said.
