Iran’s Foreign Minister Abbas Araghchi on Sunday announced he will travel to Moscow in the coming hours for urgent talks with Russian President Vladimir Putin, shortly after the United States launched airstrikes against three Iranian nuclear sites. 

Araghchi emphasized the “strategic partnership” between Iran and Russia. “We always consult with each other and coordinate our positions,” he told reporters in Istanbul, according to media reports.

Russia is a close ally of Iran. Tehran supplied Moscow with military drones to strike Ukraine and, in return, has received help with its civilian nuclear program. The Kremlin has also maintained warm relations with Israel.
