Putin Breaks Silence on US Strikes on Iran

"This is an absolutely unprovoked act of aggression against Iran; it has no basis or justification," Putin said, according to Russia's state TASS news agency.

He added that Russia was "making efforts to provide assistance to the Iranian people."

Araghchi said, ahead of his meeting with Putin, that Iran and Russia "have always had shared concerns, worries, and adversaries."

"It all depends on what Iran needs. We have offered our mediation efforts. This is concrete. We have stated our position, which is also a very important form of support for the Iranian side. Going forward, everything will depend on what Iran needs at this moment," he said, according to TASS.

When asked if Russia would supply weapons to Iran, Peskov said: "Everything depends on what the Iranian side, what our Iranian friends say."

Russia issues new warning to Trump: 'Pandora's box'

At a United Nations Security Council meeting on Sunday evening, Vassily Nebenzia, Russia's ambassador to the U.N. accused the U.S. of opening a Pandora's box with its strikes on Iran's nuclear facilities and gambling with the "safety and well-being of humanity as a whole."

"Washington reasserted that, to further the interests of its Israeli ally, it's prepared not only to turn a blind eye to the killings of tens of thousands of Palestinian women, children, and older persons but also to gamble with the safety and well-being of humanity as a whole," Nebenzia said, referring to the war in Gaza.

"Through their actions, the U.S. has opened a Pandora's box. No one knows what new catastrophes and suffering it will bring," he continued.
