Russian President Vladimir Putin has expressed support for Mojtaba Khamenei after his confirmation as the new Supreme Leader of Iran.

In a statement released by the Kremlin, Putin reiterated support for Tehran, assuring Russia “will remain a reliable partner of the Islamic Republic.”

Putin said Mojtaba assumed the role “when Iran is confronting armed aggression,” saying his work in the high office will require great courage and dedication.

The Russian leader believes 56-year-old Mojtaba will honorably continue his father’s work and unite the Iranian people “in the face of severe trials.”

Putin wished him success in solving “the difficult tasks ahead,” good health, and strength of spirit. President Masoud Pezeshkian said the appointment would strengthen national unity.

Mojtaba succeeds Ayatollah Ali Khamenei, who had held the position for 37 years, and was killed on February 28 at the start of the United States and Israel joint strikes.

The Fatemiyoun Brigade has pledged loyalty to Mojtaba. Composed mostly of Afghan fighters and organized by Iran’s Revolutionary Guard, it vowed to stand with Iran and allied groups in regional conflicts.

On Monday, TASS reported the Russian government’s preparation of a draft United Nations Security Council resolution calling for a swift ceasefire in the Middle East.

The draft expresses “deep concern over the current military escalation” in the region and beyond, and urges all parties to “immediately stop their military activities.”

Moscow wants the warring countries to refrain from further escalation and encourages a quick return to negotiations through political and diplomatic means.
