The 8 executed men had been arrested in the aftermath of the June 2017 twin attacks on Iranian Parliament building and the Mausoleum of late founder of the Islamic Republic of Iran Ayatollah Khomeini in Tehran.
The men executed on Saturday were Soleiman Mozzaffari, Esmaeil Soufi, Rahman Behrooz, Majed Moretezaei, Sirous Azizi, Ayoub Esmaeili, Khosro Raemzani Mir Ahamdi, and Othman Behrooz.
They had been sentenced to death in May by Iranian Islamic Revolution Court-Tehran branch and had been convicted of financially and logistically helping the 6 ISIL attackers who were killed during the assault last year.
The Iranian Judiciary and Intelligence officials have said that five of the six attackers who died in the assault had previously fought with ISIS in the previous strongholds of the terror group, namely Mosul and Raqqa.
Of the six attackers last year, some were killed by Iranian security forces while others blew themselves up.
Different Iranian high-ranking officials have so far blamed the Saudi, American and Israeli backers of the terrorist ISIL group for Tehran attacks.
