Iran's Foreign Minister Abbas Araghchi met with Russian President Vladimir Putin in Moscow, receiving a public assurance of full support from the old-time ally.
Araghchi said Iran is 'considering a request' from the US for negotiations, blaming Trump's administration for the failure of the peace talks.
Putin promised Russia would 'do everything that serves your interests... so that peace can be achieved', as Iran continues to stand firm against the US.
The war with the US and Israel has shown the world 'Iran's true power' and the stability of its governing system, Araghchi said.
Back-channel diplomatic efforts are ongoing, with Iran passing 'written messages' to the Americans via Pakistan spelling out red lines, including nuclear issues and the Strait of Hormuz.
