The man attacked the diplomatic mission on Jan. 27, 2023, with a Kalashnikov rifle, killing a staff member and injuring two others, Tehran Police told local media in the wake of the incident.
The man was executed after the completion of relevant judicial investigations and trial process, during which he was convicted of willfully murdering an Azerbaijani national using a firearm inside the embassy, purchasing, carrying, and keeping an illegal weapon and ammunition, and disrupting public order, the Mizan news agency affiliated with the judiciary reported.
The ruling against him was also upheld by the Supreme Court of Iran, according to the report.
In the aftermath of the incident, Azerbaijan shut down its embassy in Iran. Baku described the attack as an "act of terror," but Tehran said investigations revealed that the assailant had "personal and family-related" motives.
Azerbaijan reopened the embassy at a new location in Tehran in July 2024, after nearly a year and a half, with a guarantee from Iran that it would take appropriate measures to ensure the security of the new embassy.
