The US President's cut his time in Canada short - not long after telling people to evacuate Iran's capital, Tehran.

Channel 9 chief political editor, Charles Croucher, says the whole world is watching.

"It seems, from what's coming out of America that the US aren't directly involved in whatever happens next, but it's clear that they've been told - or at least it appears they've been told - that something is about to happen."
