Mr Trump argued that the US reps once would not have been ''proportionate'' to Iran's actions. He mentioned that should he have given the final approval, things would have gone ''to a point of no return''.
Iran stated that it has collected the debris of the destroyed drone, which it shot down on Thursday, as proof that it was within its airspace.
The US has banned all american airflights from passing over the Straits of Hormuz and other airlines, including Qantas, Emirates and Etihad are also avoiding the area.
