Gas hits $4 on average in US

The average price of gasoline in the United States reached $4 per gallon as of Tuesday morning, marking a significant jump in fuel costs. The spike represents an increase of more than a dollar per gallon over the past month, driven largely by escalating tensions in the Iran conflict that began in late February. Gas prices had remained just below the $4 threshold for roughly a week before crossing it on Tuesday. The surge reflects broader market volatility tied to Middle East instability, which typically pressures global oil supplies and domestic fuel prices.
