Trump: Mojtaba Khamenei still alive in 'some form or another'

US President Donald Trump on Friday said that he believes Iranian Supreme Leader Mojtaba Khamenei is still alive in "some form or another".

The comments come following reports that Khamenei was injured in the airstrike that killed his father, Ali Khamenei.

Trump told Fox News that the US military had completely destroyed Iran in a way that "no other country had ever done". 

He stressed that "ships must show some courage and pass through the Strait of Hormuz," adding that Iran was planning to control the Middle East
