The new round of UN sanctions against Iran rule out Russia's delivery of S-300 missile defense systems to the Islamic Republic, Russian officials concluded in a report published on Friday.

"An analysis of the provisions of the UN Security Council Resolution 1929 adopted on June 9, 2010, conducted by the FSMTC experts, shows that the restrictive measures contained in the document apply to the delivery of S-300 air defense systems to Iran as well," the Federal Service on Military-Technical Cooperation said on Friday.

Resolution 1929, adopted on Wednesday, imposes a fourth round of sanctions on Iran over its nuclear program, and includes tougher financial controls and an expanded arms embargo.

Russia initially said the delivery of S-300 surface-to-air missile systems to Iran would not be affected by new UN sanctions against Iran since they are not included in the UN Register of Conventional Arms.

Moscow signed a contract on supplying Iran with at least five S-300 systems in December 2005, but delivery of the advanced weaponry has so far been delayed.

The United States and Israel, which have not ruled out an attack on Iran over its nuclear program, have urged Russia not to deliver the missiles to Tehran.

The S-300 contract is worth some $800 million, while Russian officials estimate the forfeit penalty for the S-300 contract at $400 million.
