Tehran (dpa) - Iran has placed Russian-supplied anti-aircraft missiles at one of its nuclear facilities, the Iranian news agency Fars reported Sunday.
According to Fars, the S-300 missiles were delivered by Iran's Revolutionary Guards to the Fordo uranium enrichment facility, located south of the capital Tehran.
The Russian missile systems will soon also be used to defend the country's other nuclear facilities, Fars said.
Russia began delivering the long-range surface-to-air S-300 missiles to Iran in April, and by the end of this year the contract worth 740 million euros (828 million dollars) is expected to be fulfilled.
Russia and Iran initially signed a contract to deliver several S-300 missile systems in 2007, but Moscow nixed the deal because of UN sanctions against supplying weapons to the Islamic republic.
When that contract was signed, experts assumed that the missiles would primarily be used by Iran to defend its nuclear facilities.
Last year, Iran reached an international agreement on regulating its nuclear programme to remove sanctions, and Russian President Vladimir Putin then signed a decree to allow his country to sell weapons to Iran.
