US President Donald Trump has warned that the "gloves are off" as he declares that a ceasefire between Iran and Israel is "not enough".

Speaking to media on board Air Force One, Trump stated: "We're not looking for a ceasefire, I didn't say I was looking for a ceasefire. That was Emmanuel [Macron]. Nice guy, but he doesn't get it right too often.

"But what we're looking for is better than a ceasefire. We'll come down so hard if they do anything to our people. We'll come down so hard, then the gloves are off so beautifully.

"We're looking for a real end, not a ceasefire. Something that would be permanent, giving up entirely. A complete give-up, that's possible."
