Foreign Ministry spokesman Bahran Qassemi expressed condolences to Afghanistan’s government and people over the brutal suicide bomb attack.

Qassemi voiced concern over the growing threat of terrorism in the region.

Reiterating Iran’s call for concerted efforts and global consensus to tackle the threat, the spokesman attributed terrorist group’s intensified activities by radical extremists to the support that they receive for “political purposes”.

ISIS claimed responsibility for the Monday suicide attack on Kabul’s Baqir-ul-Olum mosque, targeting Shia mourners.

Afghani police official Fraidoon Obaidi said at least 27 people were killed and 35 others sustained injuries during the raid.

The United Nations put the death toll at 32, with more than 50 people, including many children, injured. The body described the attack as “an atrocity”.

According to officials, the attacker entered the mosque shortly after midday as mourners gathered for Arbaeen.

Arbaeen is a religious mourning ritual marking 40 days after the martyrdom anniversary of Imam Hussein (AS), the third Shia imam.

On this occasion, millions of Shia Muslims as well as Sunnis and Christians march in Iraq to Karbala, where the holy shrine of Imam Hussein is located.
