Iran has rejected suggestions it is willing to discuss its missile programme with the US.
“Iran’s missiles are absolutely and under no condition negotiable with anyone or any country,” Alireza Miryousefi, a spokesman for Iran’s mission to the UN, said on Twitter.
His denial comes after Foreign Minister Mohammad Javad Zarif suggested in an interview the missiles could be up for discussion if sanctions are lifted.
The US unilaterally withdrew from a landmark 2015 nuclear deal last year and reimposed tight restrictions.
In response, Iran announced in July it has surpassed limits on enriched Uranium imopsed in the agreement. However. the country insists it is not trying to build nuclear weapons.
