Russia has decided not to sell S-300 air defense missile systems to Iran because they are subject to U.N. Security Council sanctions, Russian media reports said on Wednesday, citing the country's armed forces chief of staff.
"A decision has been made not to supply S-300s to Iran as they are definitely subject to the sanctions," Gen. Nikolai Makarov said.
"There has been an instruction from the country's leadership to stop the deliveries, and we are obeying it."
Makarov didn't give a definite response to whether the contract between Iran and Russia on those deliveries will be terminated. However, he said that "we'll see, everything depends on Iran's behavior,".
State-run Itar-Tass ran quotes from Makarov.
Russia froze the contract with Iran on the S-300 missiles earlier this year after the latest U.N. Security Council resolution imposing sanctions on Iran.
In June, Russian Foreign Minister Sergei Lavrov said a decision from Russian President Dmitry Medvedev clarifying Russia's position on weapons sales to Iran is pending.
