Mir Mohammadi was martyred during the Israeli airstrikes in Iran in June.
He was the fifth IRCS aid worker who lost his life in attacks by the Zionist regime.
Ms Forbes and Mr Chapagain conveyed their condolences in a formal letter to Dr Pir Hossein Kolivand, President of the IRCS.
The message reads as follows:
Dear Dr. Kolivand,
It is with heavy hearts that we write to you once again to express our sincere condolences, on behalf of the International Federation of Red Cross and Red Crescent Societies (IFRC), for the tragic loss of Mr. Seyed Ali Akbar Mir Mohammadi, a volunteer relief worker with the Red Crescent Society of the Islamic Republic of Iran (IRCS), who succumbed to his injuries after being rescued from under a destroyed building in Isfahan.
Seyed’s service and dedication to IRCS will always be remembered. His commitment will continue to inspire those who follow in his footsteps.
Our thoughts are with his family, loved ones, and all members of the IRCS during this difficult time.
With deepest sympathy and solidarity,
Kate Forbes Jagan Chapagain
President Secretary General
