TEHRAN (Press Shia Agency) – Iranian Foreign Ministry Spokesman Bahram Qassemi strongly condemned a suicide bombing near a gathering of Afghan clerics in Kabul on Monday, in which at least eight people were killed and many others injured.

“On the day that clerics from all Afghan cities had gathered to discuss peace in Afghanistan and condemn terror and violence in the country, the evil hands of the war-seeking terrorists committed another crime…,” Qassemi said in a statement on Monday.

He further offered his condolences to the Afghan people and government as well as the bereaved families of the victims of the “horrible crime” and said sustainable peace in Afghanistan hinges on the unity and vigilance of all political and religious groups in the country.

The Islamic Republic of Iran, as always, sides with the Afghan people and government and is ready for any kind of assistance required to restore peace and security to the country, the spokesman noted.

A suicide bomber on Monday killed at least eight people near Muslim clerics leaving a giant tent in the Afghan capital where they had gathered to denounce terrorism and call for peace, security officials said.

No group immediately claimed responsibility for the attack, which underlines a worsening security situation ahead of parliamentary and district council elections set for Oct. 20, Reuters reported.

A series of bombings in Kabul has killed dozens of people in recent months and shown no sign of easing during the Muslim holy month of Ramadan.

On Wednesday, gunmen armed with assault rifles and grenade launchers stormed the heavily fortified headquarters of the interior ministry, battling security forces for more than two hours.

In April, two explosions in Kabul killed at least 26 people, including nine journalists who had arrived to report on an initial blast and were targeted by a suicide bomber.

A week earlier, 60 people were killed and more than 100 wounded when a suicide bomber blew himself up outside a voter registration center in the city.

The Daesh (ISIS or ISIL) terrorist group has claimed many attacks in Kabul but security officials say several are much more likely to be the work of the Haqqani network.
