Gas prices rise again for second consecutive week

After eight consecutive weeks of relief at the pump, gas prices are back on the uptick once again, AAA says.

The national average for a gallon of gas rose five cents to $3.68, up from $3.63 last Sunday. In the D.C. metro area, the price increase was sharper; a gallon will cost you about $3.72 right now, up six cents from last week.

It's still far cry from the all-time high, which was reached this week three years ago. In July of 2008, the price of a gallon topped out at a national average of $4.11.

Worries over the American debt ceiling and a possible government default and concerns over the long-standing European debt crisis sent oil prices up again.
