The U.S. wants Iran to end all uranium enrichment. The European nations have yet to make clear their position. The JCPOA limited Iran to enriching uranium up to 3.67% purity -- sufficient for civilian nuclear power purposes but below the 90% purity needed for use in a weapon.

P resident Donald Trump has issued a fresh attack warning to Iran "if necessary" after Iranian Foreign Minister Abbas Araghchi stated that Tehran "cannot give up" nuclear ambition.

Iran's foreign minister told Fox News that Tehran would continue to enrich uranium as a matter of "national pride" despite damage to its nuclear facilities.
