Iranian Foreign Minister Mohammad Javad Zarif has said Iran will not yield to the greedy demands of the parties involved in the talks over its peaceful nuclear programme.
He made these remarks while talking to media on Tuesday and in response to statements of US President Barack Obama, state-run IRNA news agency reported.
Zarif said Iran has entered the talks in all sincerity and would go on with the negotiations until securing its full nuclear rights.
He said Iran would never yield to the greedy and illogical demands of the parties involved in the talks.
Referring to the Monday's remarks by Obama, he said they vividly indicated the fact that the US has been behind many direct and indirect military threats against Iran in the past decades and imposed many unfair and illegal sanctions against the Iran.
President Obama on Monday said that Iran must commit to a verifiable freeze of at least 10 years on sensitive nuclear activity for a landmark atomic deal to be reached, but the odds are still against sealing a final agreement.
Earlier on Tuesday, officials from Iran and the US begun the second day of their latest round of talks over Tehran's nuclear energy programme in the Swiss city of Montreux.
Iran and the P5+1 countries -- Britain, France, China, Russia, the US plus Germany -- are in talks to narrow their differences on outstanding issues related to Iran's nuclear energy programme.
The two sides have missed two deadlines since an interim deal was signed in November 2013. They have set July 1 as the next deadline for the deal.
