Iran's provision of around 400 missiles includes many from the Fateh-110 family of short-range ballistic weapons, such as the Zolfaghar, three Iranian sources said. This road-mobile missile is capable of striking targets at a distance of between 300 and 700 km (186 and 435 miles), experts say.

Iran's defence ministry and the Revolutionary Guards - an elite force that oversees Iran's ballistic missile programme - declined to comment. Russia's defence ministry did not immediately respond to a request for comment.

The shipments began in early January after a deal was finalised in meetings late last year between Iranian and Russian military and security officials that took place in Tehran and Moscow, one of the Iranian sources said.
