President Trump has threatened to unleash hell on Iran in forty- eight hours if its leaders don't make a deal or open up the Strait of Hormuz.

The Iranian military has credited new air defence systems with the reported downing of two American military planes on Friday. A crew member from one of the aircraft is still missing.
