In a statement issued on Wednesday, the group described the killing as an “explicit crime” and a “targeted terrorist act”.
The National Resistance Front said the incident has sparked deep anger and concern among Afghan refugees living in Iran.
General Sari, who sought refuge in Iran after the fall of Afghanistan’s former republic order to the Taliban, was killed in an attack on Wednesday evening, in central Tehran.
In recent years, he had been active in Iran advocating for the rights of former Afghan military personnel.
The group called on Iranian authorities to identify those who planned, carried out and supported the assassination and to bring them to justice.
Jamiat-e Islami: Taliban Behind the Killing
Jamiat-e Islami Afghanistan, led by Salahuddin Rabbani, also condemned the assassination in a separate statement. The party said that since the Taliban took control of Afghanistan, this was the second influential Afghan migrant figure to be targeted in the Islamic Republic of Iran.
The statement said such killings are particularly concerning when they occur in cities where Afghanistan’s political and consular missions are under Taliban control.
Jamiat-e Islami also urged Iranian authorities to take action to identify and prosecute those responsible for such attacks.
This marks the second assassination of a senior anti-Taliban commander on Iranian soil. Previously, a commander close to Ismail Khan, one of Afghanistan’s former jihadi leaders, was killed in the city of Mashhad.
