TEHRAN: Iran's ballistic missile program will not be discussed in nuclear negotiations with world powers, the deputy foreign minister said in statements published Monday.
The remarks by Abbas Araqchi, who is also Iran's lead negotiator in talks with world powers, came a week before negotiations were to resume on a comprehensive accord over Tehran's nuclear ambitions.
"Iran's defence-related issues are not up for negotiations," Araqchi said, according to media reports.
"We will not discuss any issue other than the nuclear dossier in the negotiations," he added.
US lead negotiator in the talks, Wendy Sherman, last week told a Senate hearing that Iran's ballistic missile program would be addressed in the comprehensive deal.
"The defence-related issues are a red line for Iran. We will not allow such issues to be discussed in future talks," said Araqchi.
Western nations and Israel have long suspected Iran of covertly pursuing nuclear weapons alongside its civilian program, allegations denied by Tehran.
Tehran insists its program -- boasting long-range missiles with a maximum range of 2,000 kilometres (1,200 miles), enough to reach Israel -- is an integral part of its defence doctrine.
It also denies ever seeking atomic weapons, saying its nuclear activities are for peaceful medical and energy purposes.
Iran struck an interim nuclear deal with world powers in November under which it agreed to roll back parts of its nuclear work in exchange for the release of billions of dollars in frozen assets and limited relief from crippling sanctions.
Talks on a comprehensive nuclear agreement are due to resume on February 18 in Vienna.
