PARIS European Union foreign policy chief Federica Mogherini said on Sunday it was not impossible to get a deal between world powers and Iran over its nuclear program but said tough days lay ahead as a self-imposed June 30 deadline nears.
France's foreign minister said on Saturday an accord remained elusive due to disagreements over fundamental issues, while the U.S. and Iranian top diplomats said hard work was still needed for what could be their final negotiations to bridge significant differences.
