U.S. gasoline prices have surged past $4 per gallon due to disruptions in global oil supplies caused by the Iran conflict and the effective closure of the Strait of Hormuz. President Trump plans a prime-time address to update on the situation, promising a resolution soon and a return to lower fuel prices, though experts warn prices may rise further in the short term. Meanwhile, Trump's threats to target Iranian civilian infrastructure have drawn condemnation from legal experts who warn such actions could constitute war crimes, amid ongoing regional casualties and accusations against all involved parties.
