Iran says Russia delivers first part of S-300 air defence system

DUBAI (Reuters) - Russia has sent the first part of its S-300 air defence missile system to Iran, Iranian foreign ministry spokesman Hossein Jaber Ansari was quoted as saying by Tasnim news agency on Monday.Russia says it cancelled a contract to deliver S-300s, among the world's most capable air defence systems, to Iran in 2010 under pressure from the West. But President Vladimir Putin lifted that self-imposed ban in April 2015 following an interim nuclear deal between Iran and world powers.
