On July 15, the Embassy of Azerbaijan in the Islamic Republic of Iran returned to work. The diplomatic mission resumed its work at a new address in the Darrus district of Tehran.

Following bilateral negotiations, it was decided to resume the work of the embassy, and the ambassador along with the current staff of the diplomatic mission are already in Iran, according to the Azerbaijani Foreign Ministry. "Iran, for its part, has taken appropriate measures to ensure the security of the new embassy building in accordance with its obligations under the Vienna Convention on Diplomatic Relations (1961)," the ministry said.
Necessary steps are being taken to organize consular services at the embassy and more information will be provided in the near future. The ministry emphasized that the reopening of the embassy will contribute to the further development of Azerbaijani-Iranian relations based on the principles of mutual respect and good neighborliness, as well as to the implementation of agreements reached between the two countries and the resolution of issues on the agenda.

In January 27, 2023, an armed attack on the Azerbaijani Embassy in Tehran resulted in the death of the head of the diplomatic mission's security service and the wounding of two other guards. Tehran police reported that the suspect had been arrested. Iranian officials condemned the incident, saying the gunman had a personal, not a political, motive. However, Azerbaijani President Ilham Aliyev called the armed attack a terrorist act. Following the attack, Seyid Abbas Mousavi, Iran's ambassador to Azerbaijan, was summoned to the Azerbaijani Foreign Ministry. In response, Azerbaijan completely suspended the diplomatic activities of its embassy in Tehran and withdrew all its diplomats from the country. Subsequently, on April 6, Azerbaijan expelled four diplomats from the Iranian embassy. In retaliation, Iran expelled four employees of the Azerbaijani Consulate General in Tabriz on May 5.
