BOSTON (AP) — Gas prices in Massachusetts increased sharply over the past week.

AAA Southern New England reported Monday that the average price of regular gas is now about $3.60 a gallon. That's 14 cents higher than last Monday. The motor club blames the increase on higher crude oil prices.

The average price in Massachusetts is seven cents higher than the national average and 10 cents higher that the average price in the state a year ago.

AAA found self-serve regular selling as low as $3.50 a gallon and as high as $3.80 a gallon.
