Iran needs to receive concrete guarantees for supplying nuclear fuel for its research reactor in Tehran, a senior national security official said on Tuesday.

Secretary of the Supreme National Security Council Saeed Jalili made the remarks while speaking on the sidelines of a police and security gathering in the Iranian capital.

If necessary guarantees were not given to Iran, the country would have other options,” Jalili said, noting that if some (countries) failed to timely provide necessary fuel for Iran’s research reactor based on Iran’s will, then “this will add to the Iranians’ distrust in them.”

“Providing nuclear fuel for Tehran’s research reactor is not a political issue and has nothing to do with Iran’s talks with the group 5+1 member states,” said the official.

He noted that providing the fuel “is only a business matter and not even a technical or legal issue.”

As for Iran’s position on resumption of nuclear talks with the group 5+1 member states, Jalili said, “Tehran is ready to talk about its proposed package” presented to the Western states during last month’s talks in Vienna, Austria.

Jalili said that Tehran was willing to continue its talks with Western states only “over the subjects discussed in its proposed package.”

Referring to the latest talks between the two sides in Geneva, Jalili said, “The talks were scheduled to be followed up over the issues discussed in Tehran’s proposed package.”

“They (G5+1) have, apparently, faced some discussions among themselves and are not ready now,” Jalili said, adding, “Whenever they are ready to continue talks on Iran’s package of proposals, then we will welcome talking about the common concerns discussed in the package.”
