TEHRAN (FNA)- Iranian and US diplomats strongly rejected a report that the six world powers have given a dawn ultimatum to Iran to strike a deal over its nuclear program.

"Reports that the P5+1 gave Iran a dawn ultimatum are completely false," the US official said.


Earlier tonight, some western media outlets quoted a diplomat present in the nuclear talks underway in Lausanne as saying that the six world powers have told Iran it's "now or never", asking Iran to decide by "dawn".


Meantime, a source privy to the nuclear negotiations between Iran and the six world powers underway in Lausanne, Switzerland, said despite Iran's various proposals for the removal of the sanctions as enshrined under the Geneva Interim deal, the US and France are adamant to end the standoff by rejecting the offers.


"The Iranian team has taken several goodwill measures to work out a deal, but the United States and France insist on keeping the pressures in place despite the Geneva interim deal which envisaged a removal of the sanctions under a final agreement between Iran and the world powers," the source who asked to remain anonymous due to the sensitivity of the talks told FNA on Tuesday night.


Iran and its supreme leader have repeatedly stressed that removal of the sanctions are "the Islamic Republic's redline".


"Despite their earlier indications that they are ready to remove the sanctions, the US and France have once again shifted course and are adamant to accept any solution raised by the Iranian team for removing the sanctions," he reiterated.


Iran and Group 5+1 (the five permanent UN Security Council members plus Germany) started their new round of talks in Lausanne, Switzerland, on Thursday to narrow their differences over Tehran's nuclear energy program ahead of a July 1 deadline.
