US gas prices rise 9 cents over 2 weeks, to $2.43 a gallon

The average price of a gallon of regular-grade gasoline rose 9 cents nationally over the past two weeks, to $2.43.

Industry analyst Trilby Lundberg said Sunday that increased oil prices and the U.S. missile strike on a Syrian air base contributed to the rise.

She says that unless oil prices retreat quickly, consumers should expect gasoline prices to climb a few more cents.

The national average is up 33 cents per gallon over the price a year ago.
