US average gasoline prices have risen to more than $4 per gallon, according to the American Automobile Association website, amid the country's recent escalation in hostilities with Iran.
The national average price for regular grade stood at $4.0030 on Monday, as per AAA's daily posted prices.
This compares with an average of $3.9980 for Sunday, $3.8720 a week ago, $3.9510 a month ago, and $3.1410 for the year-ago period.
Prices have breached $4 per gallon for the first time in a month as renewed US-Iran hostilities threaten shortages of transportation fuels and add to inflation pressures, Bloomberg reported Monday.
