Motorists are paying for President Donald Trump’s most recent missile attack on Syria, with gas prices soaring as a result of the April 14 assault on three chemical weapons storage and research facilities near Damascus and Homs.

Pump prices are the highest they’ve been in months, throughout Georgia and the country, and fuel is expected to get more expensive this week.

The average gas price in DeKalb County on April 16 was $2.679 per gallon of regular, unleaded gasoline, making it among the highest in Georgia.

Statewide, the average gas price of $2.643 is the highest it has been since last September, when prices were recovering from Hurricane Irma.

The Auto Club Group, part of the American Automobile Association (AAA), said the weekend’s conflict in Syria, involving the United Kingdom and France, sent crude prices to their highest point in more than three years.

“Motorists should expect a 15-cent increase at the pump in the short term,” said Auto Club Group spokesman Mark Jenkins said April 16. “However, prices could rise even more, depending on how the crude market responds to the latest news of a U.S. missile strike over the weekend,” he said.

The U.K., France and U.S. launched more than 100 missiles at three Syrian chemical weapons storage and research facilities early Saturday local time, in retaliation against the Syrian government’s chemical weapons program.

Although Syria has not exported oil since civil war broke out in 2011, crude prices are climbing due to the potential of U.S. sanctions against Syria’s sponsors, Russia and Iran.

Syria receives fuel deliveries from Iran.

Last week crude prices rose more than $5, the largest weekly increase in more than eight months, closing on Friday at $67.39 per barrel – the highest daily settlement since December 2014.

Wholesale gasoline prices responded in kind, rising nearly 15 cents.

The average per-gallon gas price on April 16 was $2.740 in Fulton County; $2.683 in Clayton; $2.679 in DeKalb; $2.678 in Henry; $2.666 in Cobb; $2.665 in Rockdale and $2.655 in Gwinnett.

The same-day Georgia average was $2.643, and the national average $2.714.

A month ago Georgia motorists paid an average of $2.392, and a year ago an average gallon statewide cost $2.289.

The highest average per-gallon price in Georgia was $4.164 in September 2008.

The Auto Club Group said the national average price for gasoline is now the highest in more than two years.

A month ago the national average was $2.527 and a year ago it was $2.406.
