Washington - Tension with Iran and "uncertainty" in the region is adding a $20 or $30 premium to oil prices, pushing up domestic gas prices in the United States, President Barack Obama said.
"The key thing that is driving higher gas prices is actually the world's oil markets and uncertainty about what's going on in Iran and the Middle East, and that's adding a $20 or $30 premium to oil prices," Obama said in an interview with the American Automobile Association.
