**伊朗核谈判延至星期五**
美国星期二表示，伊朗和六大国同意将伊朗核谈判延长到星期五，为谈判达成最后协议提供更多时间。
美国代表团发言人哈夫说，“我们在各方面都取得了重大进展，但是本星期的工作是高技术性的，对所涉及的所有国家都至关重要。”哈夫还说，“坦率地说， 我们更关注协议的质量而不是时间。 ”
欧盟外交政策专员莫格里尼星期二早些时候说：“我们对最后期限有灵活的解释，这意味着如果最后敲定协议需要时间，需要几天的时间，我们就要花这些时间。”他说，还有几个棘手的问题有待解决。
Iran Nuclear Talks to Continue Through Friday
An interim nuclear agreement between Iran and six major powers will be extended through Friday to provide more time for talks on a final agreement, the United States said Tuesday.
"We have made substantial progress in every area, but this work is highly technical and high stakes for all of the countries involved," said U.S. delegation spokeswoman Marie Harf.
"We are frankly more concerned about the quality of the deal than we are about the clock ..." Harf's statement said.
EU foreign policy chief Federica Mogherini said earlier Tuesday, "We are interpreting in a flexible way our deadline, which means that we are taking the time, the days we still need, to finalize the agreement," adding several difficult issues to resolve remain.
