DUBAI: Iran negotiated with Russia at the weekend over buying an upgraded version of the S-300 surface-to-air missile defence system, which it requires to meet its military needs, a foreign ministry spokesman in Tehran was quoted as saying.
Iran was blocked from obtaining the S-300 before it reached a deal with world powers last July on curbing its nuclear programme, with Russia having cancelled a contract to deliver an older version of the system in 2010 under pressure from the West.
