Russia has delivered over half of the agreed number of S-300 air defense systems to Iran, Russian presidential aide Vladimir Kozhin told Sputnik on Tuesday.

In August, Iranian Defense Minister Hussein Dehqan said that Tehran was expecting Moscow to fulfill its commitments on the deliveries of S-300 air defense systems within September, adding that the main part of the batch had arrived in Iran.

“We have delivered half already, even more,” Kozhin said. The $800-million Moscow-Tehran contract to deliver Russian-made S-300 air defense systems to Iran was signed in 2007. In 2011, Iran sued Russia in the Geneva Arbitration Court after Moscow suspended the contract in 2010, citing a UN Security Council resolution that placed an arms embargo on Tehran. Russian President Vladimir Putin lifted the S-300 delivery ban in April 2015, shortly after the P5+1 group of international negotiators and Iran reached a framework nuclear agreement to remove all economic sanctions against Tehran in exchange for its pledge to ensure that all nuclear research in the country should serve exclusively peaceful purposes.
