France, Germany, Britain and the European Union say they are "extremely concerned" about Iran's renewed uranium enrichment activities and what they call "regrettable acceleration of Iran's disengagement" from commitments it made under the 2015 agreement regarding the country's nuclear program.

In a joint statement released Monday, the foreign ministers urged Iran to reverse all of the measures it has taken that go against those imposed in the Joint Comprehensive Plan of Action, which limited Iran's nuclear activity in exchange for sanctions relief.

Iran has restarted enrichment at its Fordow facility, exceeded limits on enrichment levels and the amount of enriched material it is allowed to stockpile, while also announcing work on developing more advanced centrifuges.  Iranian President Hassan Rouhani said the steps are reversible if the other signatories to the agreement help Iran work around U.S. sanctions.

In their statement, France, Germany Britain and the EU said their side has "fully upheld" their commitments under the agreement, including lifting the sanctions they had imposed over concerns Iran was working to develop nuclear weapons.  Iran says its nuclear program is only for peaceful purposes.

The deal originally also included China, Russia and the United States.  U.S. President Donald Trump withdrew from the agreement last year.
