(Las Vegas, NV)  –  An oil refinery fire in Northern California is sending Las Vegas gas prices higher.

AAA says the price for a gallon of regular is nearly $3.45.  That’s up three cents from yesterday.

The blaze broke out earlier this week at the Chevron refinery in Richmond, forcing it to shut down.

A cause remains under investigation, and an official says it will take some time to “truly assess” the amount of damage.
