Iranian Foreign Minister Mohammad Javad Zarif has voiced doubt about Washington\'s determination to reach an agreement on Iran\'s nuclear energy program. Iran\'s foreign minister said Washington\'s talk about new sanctions in recent months has caused a great deal of concern in Iran about whether the U-S is serious about wanting to reach an agreement. He said it is still possible to reach a deal on Iran\'s nuclear energy program because they have no other option and the only way to resolve the issue is through negotiations. Zarif made the remarks on the first day of talks in Vienna between Iran and the five permanent members of the UN Security Council plus Germany on reaching a permanent agreement on Iran\'s nuclear program. Earlier, Zarif said that the deal is achievable but would take more than one or two sittings to reach. Show Less >>
