Ali Maisam Nazary, Head of Foreign Relations of the National Resistance Front (NRF), expressed sympathy with those affected by the attack at a concert hall in Moscow.
Nazary stated that the "occupation" of Afghanistan by the Taliban and "21 other regional and global terrorist networks" poses a direct threat to everyone.
In a note on X social media platform, he wrote that it is imperative for the international community to unite against the "common enemy" to ensure global security for all.
The shooting and explosion on Friday night at a concert hall in Moscow has so far left at least over 100 dead and nearly 150 wounded.
The ISIS group has claimed responsibility for the attack.
Last month, Russian security agencies said that they had thwarted an attack by an ISIS branch.
At the same time, the US Embassy in Russia had also warned of a "potential extremist attack" in Moscow and advised US citizens to avoid participating in gatherings in the city.
