Benchmark crude rose 21 cents Tuesday to $99.89 per barrel in New York. Brent crude rose 2 cents to $107.98 per barrel in London.

Tensions in the Middle East have also boosted prices. Violence in Iraq and a diplomatic standoff over Iran's nuclear ambitions have stoked worries about crude supplies in the region.
At the pump, the national average for a gallon of regular gasoline was $3.23.
