"We do not conceal the fact that we seek to boost the power of our missile systems. As long as the US and the Zionist regime threaten us, we will work on our missile systems which are used for defensive purposes," Xinhua quoted Larijani, as saying.
Larijani also turned down allegations made by the US and Israel about Iran's missile program. He added that the country has made short and medium-range missiles merely to defend itself against possible aggressions.
Meanwhile the Aerospace Commander of the Islamic Revolution Guards Corps (IRGC) Amir Ali Hadgizadeh has admitted that Iran had shot down many western drones, including two in Persian Gulf.
Iran has made progress in the past decades over the development of the medium and long-range missiles, but it maintained that its missile capability is "a defensive tool against invasions."
