"There will be no return to previous oil prices or to the previous order until our will is fulfilled," said Ebrahim Zolfaghari, spokesman for Iran's central Khatam al-Anbiya headquarters, Fars reports.

"This will happen when the thought of taking action against the Iranian nation is completely erased from your dirty minds. Our first and last words, from the very first day, have been, are, and will be: no one like us will get along with someone like you. Not now, not ever," media outlets quote Zolfaghari as saying.

"Has the level of your internal conflicts reached the point of negotiating with yourselves? Do not call your failure an agreement," he added.

Earlier, media reports indicated that the U.S. had presented Iran with a list of 15 demands, including, among others, abandoning the development of nuclear weapons, reducing uranium enrichment to civilian levels, and opening the Strait of Hormuz.
