Six countries trying to address concerns about Iran's nuclear programme met in Germany on Wednesday, but the German government said it has received no official word yet on new proposals that Tehran is pledging to make. The meeting was taking place at an undisclosed location near Frankfurt and involved political directors Foreign Ministry officials below ministerial level from the US, France, Britain, Russia, China and Germany. German Foreign Ministry spokesman Jens Ploetner told reporters no concrete decisions were expected to come out of the meeting. It is much more a chance for joint assessment of the situation and to consult on possible negotiating options in the coming months, Ploetner said. On Tuesday, Iran's main nuclear negotiator, Saeed Jalili, told reporters his nation would present new proposals and will open talks in order to ease common concerns in the international arena. Western nations and others worry Iran is moving towards development of nuclear warheads. But Iranian leaders say the country only seeks reactors to produce electricity.
