Iran could easily abandon its nuclear deal with world powers within hours if the United States sticks to its policies of "sanctions and coercion", President Hassan Rouhani warned on Tuesday. 

"The failed experience of sanctions and coercion brought their previous administrations to the negotiating table," Rouhani told parliament in a televised speech. 

"If they want to go back to that experience, definitely in a short time -- not weeks or months, but in the scale of hours and days -- we will return to our previous situation very much more stronger."
