伊朗和六个世界大国的代表在土耳其的伊斯坦布尔结束了伊朗核项目谈判的第一次会谈。据报导，会谈没有取得任何进展。
谈判人员星期五在午餐前进行了长达两个小时的会谈。路透社说，伊朗没有表现出作出让步的迹象。
计划在星期五和星期六举行的谈判包括联合国安理会五个常任理事国加德国，也就是所谓5常加1。
伊朗官员说，会谈是在“积极的氛围”中开始的。伊朗国营媒体援引一位参与会谈的伊朗官员的话说，伊朗的核权利不是辩论中的“一个议题”。
一名美国国务院发言人星期四说，美国并不期待这次伊斯坦布尔会谈能有任何“重大突破”。但是他说，美国的谈判人员希望讨论一项核燃料交换计划。这项计划已经被更新，反应了伊朗自2009以来在铀浓缩方面的进展。
Representatives from Iran and six world powers have ended a first meeting in Turkey to discuss Tehran's controversial nuclear program with no reported progress.
Negotiators held a two-hour meeting in Istanbul Friday before breaking for lunch. Reuters news agency says Iran gave no indication that it was willing to make concessions.
The talks scheduled for Friday and Saturday include the five permanent members of the U.N. Security Council and Germany, a group known as the P5 + 1.
Iranian officials said the talks started in a "positive atmosphere." Iranian state-run media quote an official attending the talks as saying his country's nuclear rights have "not been an issue" in the debate.
On Thursday, a U.S. State Department spokesman says the United States does not expect any "big breakthroughs" in Istanbul. But he says U.S. negotiators were willing to discuss a nuclear fuel swap proposal updated to reflect Iran's progress in enrichment since 2009.
