Moscow, April 16 (Inditop) There are no obstacles to the delivery of Russian S-300 surface-to-air missile systems to Tehran, Iran’s deputy foreign minister has said.

“There are no problems with this (S-300) contract,” Mehdi Safari said Wednesday at the end of his visit to Moscow.

He offered no specifics about the contract’s implementation, but dismissed concerns raised by a number of countries over S-300 deliveries to Iran.

“After all, these are purely defensive weapons, and any country has the right to buy them. I believe this could only worry those states that have plans to attack others,” he said.

A Russian arms export official said last month Iran had not yet received any S-300 air defence systems.

Iranian media, citing senior security officials, reported that Russia has started delivering elements of the advanced version of the S-300 missile to Tehran under a 2007 contract.

The latest version of the S-300 missile has a range of up to 195 km and can intercept aircraft and ballistic missiles.

It is considered one of the world’s most effective all-altitude regional air defence systems, comparable in performance to the US MIM-104 Patriot system.

Iran recently took delivery of 29 Russian-made Tor-M1 air defence missile systems under a $700-million contract signed in late 2005.
