Pakistan, Feb. 11 -- Iran has declared its missile capabilities a red line and said they will not be part of any negotiations, an adviser to Supreme Leader Ayatollah Ali Khamenei said Wednesday. Ali Shamkhani made the statement during a march marking the 47th anniversary of the Islamic Revolution. The remarks come as Washington and Tehran prepare for a new round of diplomacy to prevent conflict.

The US has sought to expand nuclear talks to include restrictions on Iran's missile program amid a regional naval buildup. Shamkhani emphasized that while Iran is willing to discuss curbs on its nuclear program in exchange for sanctions relief, its missile capabilities are non-negotiable.
