The White House has turned down Iran's 14-point peace proposal, the Tehran Times reported, citing an official response in which Washington declared all Iranian points unacceptable.
The US continues to maintain a harsh stance toward Tehran, including on the nuclear issue, according to the publication.
If Washington had responded positively, Iran would have been prepared to move to a second phase of consultations, including discussions on the nuclear dossier.
Tehran's peace plan, presented to the US in early May, called for a complete end to the military conflict within a month, the lifting of the blockade on Iranian ports, the removal of restrictions, and the payment of compensation.
