Iran rejects Obama's demand for 10-year nuclear halt work: Fars agency

"Obama’s stance ... is expressed in unacceptable and threatening phrases ... Iran will not accept excessive and illogical demands ... Tehran will continue nuclear negotiations with the six powers," Foreign Minister Mohammad Javad Zarif was quoted as saying by Fars.

In an interview with Reuters on Monday, Obama said Iran must commit to a verifiable halt of at least 10 years on sensitive nuclear work for a landmark atomic deal to be reached between Tehran and six major powers.
