"According to the S-300 contract, our country should take legal action in accordance with the contents of the deal in a bid to restore the inalienable rights of the Islamic Republic of Iran," Kazzem Jalali, spokesman for the parliament's National Security and Foreign Policy Commission, told the Fars news agency.
Certain powers out to harm ties between Tehran and Moscow are the reason Russia failed to deliver the S-300 air defense system, Iran's Defense Minister General Ahmad Vahidi told reporters Monday shortly after arriving in Azerbaijan for a visit.
"The contract for purchasing S-300 systems does not violate laws or the international obligations of either party and this has been explicitly included in the aforementioned contract," he told Iran's Press TV.
Russia should have delivered the missile defense system to Iran in 2008, two years before the United Nations Security Council passed resolution 1929 in June this year, ISNA, the Iranian students news agency, quoted the defense minister saying.
The $800 million contract signed in 2007 requires Russia to provide Iran with at least five S-300 systems, the Iranian television network said.
