The sale of Russian S-400 systems has already resulted in issues, as Turkey has come under criticism and restrictions from the US after Ankara made it clear that it would proceed with its acquisition of the Russian air defences in accordance with a deal concluded back in 2017.
Bloomberg said Thursday, citing its sources, that Russia had refused to sell Iran its S-400 air defence systems. According to the agency, Russia explained its decision by saying that such a move would escalate tensions in the region.
The Russian Ministry of Defence hasn't commented on the issue yet, Sputnik reports.
