Gas prices in Washington are on the rise, alongside the rest of the nation, as tensions are escalating in the Middle East after the U.S. and Israel carried out air strikes on Iran over the weekend.
Washington residents are paying nearly 46% more per gallon of gas than the rest of the country, with prices increasing by nearly 43 cents since just a month ago, according to AAA.
The conflict began early Saturday morning with the killing of Iranian Supreme Leader Ayatollah Ali Khamenei in a joint U.S.-Israeli strike that reverberated around the globe.
The war in the Middle East continued on multiple fronts into Monday as attacks from Iran and Iranian-backed militias struck Israel and Arab states as well as U.S. military targets in the region.
As of March 2, Washington’s average price per gallon is $4.369, which is $1.372 higher than the national average. The price per gallon in Washington is the third highest in the nation.
Across the greater Seattle area, the average price per gallon of regular gas is $4.585, a whopping 53% higher than the national average.

Global oil prices surge following Iran-U.S. war
Oil prices rose sharply on Monday as disruptions to tanker traffic through the Strait of Hormuz chokepoint raised uncertainty about how U.S. and Israeli attacks on Iran would affect supply to the world economy.
U.S. oil traded 8.40% higher at $72.63 per barrel, while international standard Brent was up 8.5% at $79.13 per barrel.
A key focus was the Strait at the southern end of the Persian Gulf, through which 20% of the world’s oil supply passes.
The UK Maritime Trade Operations Centre reported attacks on several vessels in the area on either side of the Strait and warned of elevated electronic interference to systems that show where ships are. A bomb-carrying drone boat struck a Marshall Islands-flagged oil tanker in the Gulf of Oman on Monday, killing one mariner, Oman confirmed.
