In an about-face, Russia said Friday it will delay delivery of an air defence system to Iran after the UN Security Council resolution for further sanctions on Tehran, officials said, DPA reported.
President Dmitry Medvedev was drawing up an edict containing a list of all weapons whose export to Tehran would be forbidden, the news agency Interfax reported.
Friday's development comes just a day after the Foreign Ministry had said the council's resolution would have "no influence" on Russia's delivery of the S-300 air defence system to Tehran.
Iran wanted to prevent a possible airstrike on its nuclear facilities with the system.
Under pressure from Israel, Russia has until now put off delivering the S-300 system, despite having a contract with Tehran.
The UN Security Council on Wednesday voted to impose further sanctions on Iran which it accuses of trying to develop nuclear weapons. Russia, which could have vetoed the resolution, also voted in favour.
Tanks, rockets and cruisers are all now among the military equipment whose sale is forbidden to Iran.
