BERLIN (REUTERS) - The European Union and the foreign ministers of Germany, France and Britain on Thursday (May 9) said they were still committed to the Iran nuclear deal, but would not accept ultimatums after Iran announced it was scaling back curbs to its nuclear programme.

"We reject any ultimatums and we will assess Iran's compliance on the basis of Iran's performance regarding its nuclear-related commitments under the JCPOA and the NPT (Treaty on the Non-Proliferation of Nuclear Weapons)," the statement read, with JCPOA referring to the Iran nuclear deal.

They said they regretted the reimposition of sanctions by the United States after it withdrew from the nuclear deal and added that they remained committed to preserving and fully implementing the Iran nuclear deal.
