US President Donald Trump on Sunday responded to Iran's Supreme Leader Ayatollah Ali Khamenei after he warned a US strike on Iran would trigger a regional war.

"Why wouldn’t he say that? Of course, he is going to say that," Trump told reporters during his visit to Mar-a-Lago.

"We have the biggest, most powerful ships in the world over there, very close," Trump said, adding, "Hopefully, we’ll make a deal."

In case of a no-deal, Trump said, "then we'll find out whether or not he was right."
