Crude oil futures jumped more than 3% Sunday after Israel struck two natural gas facilities in Iran, raising fears that the war will expand to energy infrastructure and disrupt supplies in the region.

US and Brent crude prices jumped on fears of supply disruption from the Middle East as Iran has repeatedly threatened to close a key shipping route.

U.S. oil prices already jumped last week, which could cause prices at the pump to rise about 20 cents a gallon in the coming weeks, according to one estimate.
