Iran's President Hassan Rouhani, right, shakes hands with Director General of the International Atomic Energy Agency Yukiya Amano at the start of their meeting in Tehran.
Iranian President Hassan Rouhani told the visiting head of the UN nuclear watchdog on Sunday that Tehran will not discuss its long-range missile program as part of talks aimed at resolving a decade-long nuclear dispute, official media reported.
"Iran's missile power is not negotiable in any level under any pretext," Rouhani told Yukiya Amano, the director-general of the International Atomic Energy Agency, the official IRNA news service reported.
The president added, however, that Iran is prepared to cooperate with the IAEA's probe into whether its civilian nuclear program has a military component, "since there is no room for using a weapon of mass destruction in Iran's defense doctrine."
Western nations have long suspected Iran of covertly seeking a nuclear weapons capability, accusations denied by Iran, which insists its nuclear program is only for civilian purposes like power generation and the production of medical isotopes.
Iran's long-range missile program has long been a major concern for Israel, which fears it may one day mount nuclear warheads on the projectiles and has not ruled out military action to prevent that from happening. Iran insists the missile program is a vital deterrent to a possible Israeli attack.
Amano's visit comes as world powers continue to negotiate with the Islamic Republic in hopes of reaching a permanent deal to curb its nuclear ambitions in exchange for the lifting of crippling international sanctions.
Amano landed in Tehran late Saturday and has been holding talks with Iranian officials, state media reported.
The IAEA is trying to investigate allegations that Iran secretly worked on nuclear weapons -- something Tehran denies. The US and its allies insist that any overall nuclear agreement with the Islamic Republic must include a conclusion by the agency that Iran has fully cooperated with its probe.
