The European trio's accusation that Iran violates the key restrictions of the nuclear deal are unjustified, the Russian Foreign Ministry said urging the countries not to increase tensions that could endanger the pact.

Paris, Berlin and London officially reported Iran's non-compliance with the 2015 agreement to the Joint Commission under the Dispute Resolution Mechanism. This step could potentially lead to the UN Security Council being forced to decide on whether or not to bring back sanctions against Tehran.

Russia's Foreign Ministry said in a statement:
"We can't rule out that the ill-considered actions of the European trio will lead to a new escalation around the JCPOA (Joint Comprehensive Plan of Action) and make the return to the implementation of the 'nuclear deal' in its initially agreed format unachievable."
Iran rolled back on its uranium enrichment constraints detailed in the international agreement earlier this month after one of its top military commanders, Qassem Soleimani, was assassinated in an American drone strike in Iraq.

Tehran's decision to put its commitments on hold was a response to the actions of the US, which unilaterally withdrew from the deal in May 2018 and reintroduced restrictions against Iran, the ministry reminded. However, the country keeps allowing the International Atomic Energy Agency (IAEA) monitors to its nuclear sites - and "the transparency of the Iranian nuclear program has been one of the key clauses of the nuclear deal."

Despite vocally rejecting the US campaign of "maximum pressure" on Iran, France, Germany and the UK are "either not ready or can't afford to" work on finding effective ways of bypassing the hurdles to the deal created by Washington.

There are also "serious problems" with implementing the side of the deal on the part of the European trio, the ministry said. When all those issues are settled, "Iran would have no reason to retract from the initially agreed framework of the JCPOA."
