Reuters: Iran on Tuesday rejected as “unacceptable” U.S. President Barack Obama’s demand that it freeze sensitive nuclear activities for at least 10 years, but said it would continue talks aimed at securing a deal, Iran’s semi-official Fars news agency reported.

“Iran will not accept excessive and illogical demands,” Iranian Foreign Minister Mohammad Javad Zarif was quoted as saying by Fars.

“Obama’s stance … is expressed in unacceptable and threatening phrases … ,” he reportedly said, adding that negotiations underway in Switzerland would nonetheless carry on.
