"The West has changed its attitude in the nuclear talks. This issue has decelerated the pace of progress," the source added, Iran`s Fars news agency reported July 10.
"They started to change their attitude once the Lausanne agreement was declared. Since then, we have seeing changes in a lot of issues, from sanctions to the period of agreement to nuclear issues."
"We need reliable guarantees from the West. Our feeling is that they are trying to maintain sanctions instead of lifting them," the Iranian official said, adding some people in the US have got used to the sanctions and do not know how they can get rid of them.
The official further said that the US should take decisions seriously,
"Iran has always been committed to its obligations. But, we have not seen mutual commitment by the US".
The Islamic Republic`s principal attitude has not changed, the official emphasized. He underlined that a comprehensive agreement is within reach, provided that delusions are abandoned.
"Any agreement should be balanced, based on justice and fairness. The other side should show courage," the source said.
Iran and the P5 1 countries - the United States, Britain, France, Russia, China and Germany - have been engaged in talks in Vienna towards reaching a landmark agreement over Tehran`s nuclear program.
The deal`s deadline has been extended twice, and both U.S. and Iranian officials have said differences remain ahead of a third deadline on July 10.
