"We have repeatedly said that we do not plan to supply those types of weapons to countries located in volatile regions," spokesman Andrei Nesterenko was quoted as saying by the RIA Novosti news agency.

Such a move would "run contrary to both Russia's foreign policy and its interest in maintaining stability in different regions," said the spokesman.

"Any country can decide to purchase some types of Russian weapons, but we made decisions at the top political level," he said, adding that decisions are based on the need to maintain a balance of forces and regional security.

Israeli media reported earlier that the Israeli Defense Ministry was concerned about news of Russia's plans to sell missile systems to Iran.

The Russian arms export monopoly Rosoboronexport said Monday it could provide no details about any plan to sell Russian surface-to-air missiles to the Middle East region.
