Russia lifts ban on S-300 missile system delivery to Iran
Delivery of the S-300s was cancelled in 2010 after the UN imposed sanctions on Iran over its nuclear programme.
But the Russian president gave the go-ahead after Tehran struck an interim deal with world powers to curb nuclear activities in exchange for sanctions relief.
The US and Israel have criticised the news.
When it was cancelled, Iran filed a lawsuit seeking billions of dollars in damages.
The S-300 is a surface-to-air missile system that can be used against multiple targets including jets, or to shoot down other missiles.
It is not clear when the system would be delivered. Russia has stopped producing the model specified under the original contract and has instead offered an upgrade.
