Russian President Vladimir Putin has signed a decree to lift the ban on supplies of S-300 air defense missile systems to Iran.

"The decree cancels the ban from transit through Russia (including by air), transportation outside the territory of Russia to the Islamic Republic of Iran and also handover to the Islamic Republic of Iran outside the territory of Russia with the use of ships and aircraft flying the Russian state flag of the air defense missile systems S-300," the Kremlin’s press-service has said.

Russia"s contract on S-300 supplies to Iran was suspended after the UN imposed sanctions against Tehran in 2010.
