"When they say that our options are always on the table, they should pay attention that in reaction Iran should always be watchful to prevent any possible harm against the country," Larijani said in a press conference in Tehran on Saturday.
He, meantime, downplayed the US officials threats against Iran, and said "The Americans arent allowed to interfere in our countrys internal affairs."
Asked if he will facilitate parliamentary relations between Tehran and Washington after the two countries diplomats held several bilateral meetings on the nuclear issue in the last few months, Larijani said such a plan has never been an agenda, reiterating that the two sides are only dealing with Irans nuclear issue in their talks.
After Iran and the world powers struck a deal in November, Washington officials have been making increasing provocative remarks against Iran and the deal. US Secretary of State John Kerry said in an interview in Geneva in January that the military option was still on the table if Iran did not live up to its nuclear commitments under the Geneva deal.
In response, a large number of Iranian officials have warned of the dire repercussions of such remarks by Washington officials. Lieutenant Commander of the Islamic Revolution Guards Corps (IRGC) Brigadier General Hossein Salami warned that the slightest military move by the US will be reciprocated by Irans harshest response, underlining that Irans reaction would "recognize no boundary".
