Dear Mr President,
I was deeply saddened by the news of heavy casualties as a result of an explosion in a coal mine in Golestan province.
On the occasion of this tragedy, on behalf of the people of Azerbaijan and on my own behalf, I extend my deepest condolences to you, families and loved ones of those who died and the whole people of Iran and wish those injured the soonest possible recovery.
May Allah rest the souls of the dead in peace!
President of the Republic of Azerbaijan
