U.S President Donald Trump said on Wednesday that an interim accord with Iran was not final, and that he could resume a bombing campaign if he did not like it or if Tehran did not "behave".

"It's a memorandum of understanding. And if I don't like it, we'll go back to shooting at them, dropping bombs on their head. If I don't like it, if they don't behave, we'll go right back to dropping bombs right smack in the middle of their head, OK?" Trump said on the sidelines of a G7 summit in France.

Trump said the Iran memorandum of understanding did not include immediate sanctions relief for Iran.

Trump heaped praise on the framework agreement that his administration had negotiated, saying: "That's a very strong deal. Nobody knows what it is, but it's very strong, and most people seem to be very happy."
