Russia warned Israel against its strikes on Iranian nuclear sites, saying it puts the world on the "brink of a catastrophe". Israel has struck nuclear facilities across Iran, including at Bushehr, Natanz, Isfahan, and Arak. It accuses Iran of seeking to build a nuclear bomb. Tehran says its nuclear program is for civilian energy purposes.

Russian President Vladimir Putin has offered to help mediate an end to the conflict between Israel and Iran, suggesting Moscow could help negotiate a settlement that could allow Tehran to pursue a peaceful atomic program while assuaging Israeli security concerns.

Russia's foreign ministry on Thursday warned the United States not to take military action against Iran, amid speculation over whether Washington will enter the war alongside Israel.
