西方国家拒绝接受伊朗有关立即放松对其经济制裁的要求，因此世界诸强国与伊朗就其核项目的谈判遇到阻碍。伊朗官方媒体说，必须对有关建议进行重大修正。
星期四，在巴格达进行的谈判进入第二天。美国和欧盟官员说，他们仍在努力寻找打破僵局的途径。
西方国家的谈判代表星期三提出一项方案，要求德黑兰停止生产纯度为20%的铀，并寻求伊朗关闭一个铀浓缩设施。
作为交换条件，联合国安理会五个常任理事国和德国(五常加一)提出为伊朗提供医用同位素、一些核安全合作以及民航飞机零配件。
伊朗方面表示，西方国家结束对德黑兰的石油贸易制裁是谈判能否取得进展的关键。但是，五常加一的外交官拒绝考虑延缓对伊朗实施更严厉的制裁。
Continuing talks between Iran and global powers have hit a snag as the West rebuffed Tehran's call for an immediate easing of economic sanctions and official Iranian media said the proposals on the table needed to be significantly revised.
The negotiations in Baghdad were extended for a second day into Thursday, as U.S. and European officials said they remained committed to finding a solution to the impasse.
Western representatives presented a package Wednesday that calls on Tehran to freeze production of nuclear fuel enriched to 20 percent purity and to close an Iranian enrichment facility
In exchange, the P5+1 group offered benefits, including medical isotopes, some nuclear safety cooperation and spare parts for civilian airliners, much needed in Iran. The P5+1 includes the five permanent members of the U.N. Security Council plus Germany.
The Iranian side indicated that ending impending Western sanctions on Tehran's oil trade is key for the talks to advance. But diplomats from the six world powers have refused to consider postponing the new harsher measures.
