Trump told NBC that intelligence suggests the new Iranian supreme leader Mojtaba Khamenei may no longer be alive.

"I do not know if he is even alive. So far nobody has managed to film him," Trump said. He added that if Khamenei is alive, he should "do something very smart for his country, and that is to surrender."

The statement comes in the context of escalating US-Iran tensions, accompanied by military strikes and aggressive rhetoric.
