LAUSANNE, Switzerland (Reuters) - A framework was reached at marathon talks on Iran's nuclear programme in Switzerland that will allow further negotiations towards a final agreement, Germany and Iran said, although it was not clear what details would be made public. Western and Iranian officials at the talks said they would conclude with a joint statement announcing that enough progress had been reached to allow further negotiations until a final deadline of June 30. "Agreement on framework for final agreement reached. Press conference following," Germany's foreign ministry said on Twitter.
