Iran's defense minister has criticized Russia for its decision to ban sales of an air defense missile system to Tehran.
Iran's state-run TV quotes General Ahmad Vahidi on Thursday as saying Moscow wilted under international pressure on its commitments to Iran.
He also said Iran is planning to build its own advanced anti-aircraft missile system, after Russia canceled all sales of its S-300 system to Tehran.
Russian President Dmitry Medvedev announced the decision Wednesday. The Kremlin says the Russian leader also decided to ban the sale of tanks, aircraft and sea vessels to Iran.
The ban is in response to United Nations sanctions imposed in June for Iran's refusal to stop enriching uranium.
Iran says its nuclear program is peaceful. Western powers have accused Iran of trying to develop nuclear weapons
Western nations had criticized Moscow for its intent to provide Iran with the missile system, saying the equipment would give Iran the means to withstand air strikes against it nuclear sites.
