Referring to the US administration’s domestic problems in dealing with Iran’s peaceful nuclear energy program, Zarif added the US must make a “very tough” decision.

“I feel that the US administration, due to its domestic problems, makes remarks which are based on prejudgment,” Zarif said at a joint press conference with visiting Greek Foreign Minister Evangelos Venizelos in Tehran on Saturday.

The top Iranian diplomat made the comments in reaction to the latest remarks by US Secretary of State John Kerry who said on Thursday that Iran has to take some "tough decisions" in order to hammer out a comprehensive deal with major world powers.

"We believe we're heading in the right direction. I can't tell you where it's going to finally land, we don't know," Kerry said of the negotiations between Iran and the P5+1 group due to resume next week.

Iran and the five permanent members of the UN Security Council – Russia, China, France, Britain and the US -- plus Germany are working to hammer out a comprehensive deal following the Geneva accord. Experts from both sides met in Vienna, Austria, last week.

The next round of high-level talks between Iran and the six countries is to be held in Vienna on March 17.

Zarif said the US and the West made allegations against Iran for years, claiming that Tehran seeks to produce nuclear weapons and they are presently calling on the Islamic Republic to adopt confidence-building measures.

“They well know that we have never sought and do not seek nuclear weapons and that our nuclear program is peaceful. So, Iran has no intention of stopping any kind of its nuclear activities and the opposite side knows this,” the Iranian minister added.

“Based on our religious principles, strategic considerations and military doctrine, we have never sought to produce nuclear weapons and will not do so in the future,” he reiterated.

He called on US officials to recognize Iran’s rights.
