Moscow regrets rising tensions surrounding the Iran nuclear deal and believes that the United States’ actions are the reason, Russian Presidential Spokesman Dmitry Peskov told reporters.

Axar.az reports foreign media that "unfortunately, we are witnessing rising tensions and Iran’s decisions [to reduce its commitments to the Joint Comprehensive Plan of Action (JCPOA) - TASS]," Peskov said, adding that "Regrettably, the situation leads to further escalation."

"We clearly understand that Iran makes such decisions in response to the pressure that runs counter to the spirit and letter of the JCPOA," the Kremlin spokesman pointed out. "It is the United States that provoked Iran to take such actions," he added. "Unfortunately, concerns remain," Peskov said, noting that US Secretary of State Michael Pompeo had not given any assurances on the issue at Tuesday’s meeting with Russian President Vladimir Putin.
