Iran's Supreme Leader Ali Khamenei criticized the U.S. proposal for a nuclear deal on Wednesday and stressed Iran won't accept an agreement that makes its nuclear program dependent on other countries.

Iran’s supreme leader effectively rejected a U.S. proposal that allows temporary uranium enrichment in the country before ending it completely, forcing the White House to reconsider its approach as tensions mount over Iran’s nuclear program.

Iran is currently reviewing a formal U.S. nuclear deal proposal as both sides remain deeply divided over uranium enrichment limits and sanctions relief.
