One of the biggest concerns about the conflict now underway with Iran is -- would Iran attempt to shut down the body of water off its southwest coast, a move that could cause the price of gasoline to skyrocket.
That body of water off its coast is the Strait of Hormuz, often called a "chokepoint," which is a shipping lane for nations such as Kuwait, and should the Strait be closed the price of gas could go up considerably.
As of Saturday night, there are reports from some Middle Eastern news media that the Islamic Revolutionary Guard, a key Iran military organization, is attempting to shut the Strait down, but there's been no confirmation of that and no increase in oil prices that would reflect such a drastic move by Iran.
Reuters reports that the captains of some ships trying to get through the Strait have been receiving radio transmissions telling them the Strait has been closed.
The news agency says there have been VHF transmissions purportedly from Iran's Revolutionary Guards saying, "no ship is allowed to pass the Strait of Hormuz".
But it's not certain that these radio messages are official and no ships are reported to have been stopped while negotiating the Strait.
