Crude oil futures rose more than 1% on Thursday, after Prime Minister Benjamin Netanyahu ordered Israel’s military to intensify attacks against Iran.

The U.S. West Texas Intermediate crude for July - which did not settle on Thursday as it was a U.S. holiday and expires on Friday - was up 86 cents, or 1.1%, to $76. The more liquid WTI for August rose 0.7%, or 50 cents to $74.

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.
