Russia says it has completed the delivery of S-300 air-defense missile systems to Iran.
The Federal Service for Military-Technical Cooperation made the announcement on October 13, about six months after Moscow delivered the first part of its shipment of S-300 missile systems to Tehran.
In 2010, Moscow froze a 2007 deal to deliver S-300s to Iran under pressure from the West, but President Vladimir Putin lifted the suspension in April 2015.
The United States and Israel have expressed concern over the missile systems, fearing they could upset the regional balance of military power.
