Russia's Foreign Ministry said on Monday that it saw no threat of nuclear weapons proliferation after Iran's decision to abandon limitations on enriching uranium.
The ministry said that Russia remained fully committed to the Iran nuclear deal known as the Joint Comprehensive Plan of Action.
Iran announced on Sunday that it would lift limitations on uranium enrichment, taking a further step back from commitments to a 2015 nuclear deal with six major powers, but said it would continue to cooperate with the UN nuclear watchdog.
