Russian President Vladimir Putin has strongly denounced the assassination of Iranian Supreme Leader Ali Khamenei, labeling the incident a “cynical violation” of established norms. This event occurred amid a series of attacks attributed to Israel and the United States.

In a publicized letter to Iranian President Masoud Pezeshkian, released by the Kremlin following Khamenei’s assassination, Putin expressed his condemnation. The audacious daylight attacks on Saturday not only claimed the life of Khamenei but also resulted in the deaths of several key Iranian officials, including the leader of the Iranian Revolutionary Guard Corps.

“Accept my heartfelt condolences over the murder of the Supreme Leader of the Islamic Republic of Iran, Seyed Ali Khamenei, and his family members,” Putin articulated. “This act was committed in blatant disregard for all standards of human morality and international law.”

Putin further remarked, “In Russia, Ayatollah Khamenei will be remembered as a remarkable leader who significantly contributed to the enhancement of Russian-Iranian relations, elevating them to a comprehensive strategic partnership.”

“Please extend my deepest sympathy and support to the Supreme Leader’s family, friends, the Iranian government, and its people,” he added.

Iranian Ambassador to the United Nations Amir-Saeid Iravani condemned the joint U.S.-Israeli strikes that rained down on his country throughout Saturday during a U.N. Security Council meeting.

Iravani accused the U.S. of undermining its claims of pursuing international stability while attacking a sovereign country for its “domestic” activities.

“Neither the charter nor international law recognize internal matters of a state as justification for the use of force by other states. The rule of law would be replaced by the rule of force,” Iravani said.

“Iran will continue to exercise its right of self-defense decisively and without hesitation until the aggression ceases in full and unequivocal terms.”

On Saturday morning, President Donald Trump ordered the execution of Operation Epic Fury, citing Tehran’s continued efforts to develop a nuclear weapon.

“It has always been the policy of the United States, in particular my administration, that this terrorist regime can never have a nuclear weapon. I’ll say it again. They can never have a nuclear weapon,” Trump said in remarks about the attack Saturday.

Trump said the strikes were meant to “defend the American people by eliminating imminent threats from the Iranian regime” and that they had come after Iran had refused to abandon plans to develop nuclear capabilities.

Iravani called the attack a continuation of longstanding U.S. aggression against Iran.

“Mr. president, this morning the United States regime, jointly and in coordination with the Israeli regime, initiated an unprovoked and premeditated aggression against the Islamic Republic of Iran for the second time in recent months,” Irvani said, referring to strikes the U.S. carried out against its nuclear enrichment sites last year. “The president of the United States and the prime minister of the Israeli regime have openly claimed responsibility for this act of aggression and have explicitly articulated regime change as their objective, an unmistakable admission of their intent to violate Iran’s sovereignty and territorial integrity.”
