Moscow, Feb 25 (IANS): Russian President Vladimir Putin held telephone conversations with leaders of several countries, the Kremlin has said.

Issues relating to the diplomatic efforts to preserve and fully implement the Joint Comprehensive Plan of Action (JCPOA) on Iran's nuclear program were reviewed, the Kremlin said, adding that it was noted that reaching a final agreement on the JCPOA would contribute to regional stability and security.

The Russian President also briefed Indian Prime Minister Narendra Modi about Moscow's stance on the Ukraine issue.

"When discussing the situation, Putin outlined his fundamental assessments of Kiev's aggressive actions against the civilian population of Donbas, as well as about Kiev's many years of destructive policy aimed at breaking the Minsk agreements," the Kremlin said.
