The national average price of gasoline in the United States rises again to around $4 per gallon, multiple outlets report. Coverage links the increase to renewed tensions and attacks between the United States and Iran, which are described as intensifying or continuing. Several articles note that the $4 figure is a nationwide average, and that drivers in some states have been paying above $4 for longer. One outlet says the average had dipped in mid-June before climbing again, suggesting a recent rebound after a brief decline. The reports generally attribute the price movement to heightened geopolitical developments, though they do not provide detailed breakdowns of oil supply or specific market drivers beyond the connection to the ongoing conflict. Overall, the story focuses on the renewed increase in gasoline prices to a $4-per-gallon national average as U.S. and Iran exchanges of attacks continue.
