Moscow is ready to pool efforts with Tehran in countering the global terrorist threat, Russia's Foreign Ministry said on Thursday.
At least 38 people were killed and 50 others injured in a suicide attack in southeastern Iran on Wednesday.
It said Russia "condemns this inhuman, bloody crime" committed by extremists and "is ready to closely cooperate with the Islamic Republic of Iran."
The attack occurred in front of the Imam Hussein mosque in the city of Chabahar in the Sistan-Baluchestan province while people were gathering at a mosque for a mourning ceremony.
Iranian media said three suicide bombers were involved.
