US President Donald Trump on Tuesday described the ongoing US-Israel military operations against Iran as "proceeding very well," warning that Tehran must not be allowed to obtain nuclear weapons and that it would take atleast a decade to rebuild whatever has been destroyed in the course of bombing across the region.

"The war is proceeding very well... We can't let them have a nuclear weapon... They would have used it very gladly... We did a good job... Every time you see somebody with no legs, no arms, a face that's been really so badly damaged, lives destroyed, 95% chance it came right out of Iran," Trump said.
