Habib Farajollah Chaab was sentenced to death over his role with a separatist group alleged to have carried out a deadly attack.

Habib Farajollah Chaab was sentenced to death for being “corrupt on earth”, a capital offence under Iran’s strict Islamic laws, Reuters news agency reported.

State broadcaster IRIB reported his execution on Saturday.

“The death sentence for Habib Chaab… nicknamed Habib Asyud, the head of Harakat al-Nidal terrorist group… was executed today, Saturday morning,” the Iranian judiciary’s Mizan Online website reported.

In March, Iran’s Supreme Court upheld the Iranian-Swedish dissident’s death sentence for alleged “terrorist” activities related to the Arab separatist group known as the Arab Struggle Movement for the Liberation of Ahwaz.

Iran said in 2020 that its security forces arrested Sweden-based Chaab in Turkey and took him to Tehran, without saying where or how he was captured.
