Iran carried out the execution of Yasin Hosseinzadeh, who was found guilty of the 2023 attack on the Azerbaijani Embassy in Tehran, where he killed the security chief. Hosseinzadeh's sentencing, which marked escalating tensions between Iran and Azerbaijan, has been characterized by the Azerbaijani president as a terrorist act contrary to Iranian claims of personal motivation. Following the attack, Azerbaijan temporarily closed its embassy in Tehran and withdrew its diplomatic staff, but reopened it last year after enhanced security measures were imposed by Iran. Notably, recent diplomatic efforts indicated a potential thaw in relations, as both countries conducted joint military exercises and expressed a desire for improved ties.

Iran Executes Man for 2023 Attack on Azerbaijani Embassy
Iran has executed a man convicted of murdering the head of security at the Azerbaijani Embassy, straining relations between the two countries.
Iran executed a man on Wednesday who was convicted of murdering the head of security at the Azerbaijani Embassy during a deadly attack in 2023. The assailant, Yasin Hosseinzadeh, reportedly stormed the embassy with an AK-47, allegedly believing his wife was inside and refusing to meet him. This incident escalated already strained relations between Iran and Azerbaijan, particularly due to Iran's support of Armenia in their longstanding territorial disputes and Azerbaijan's ties with Turkey and Israel. Although relations appeared to improve following a recent meeting between President Ilham Aliyev of Azerbaijan and President Masoud Pezeshkian of Iran, the initial diplomatic fallout led to the temporary closure of the Azerbaijani embassy in Tehran. Azerbaijan's foreign ministry revealed that the embassy reopened last year after security upgrades were made. Concurrently, both nations conducted joint military drills this week, signifying a possible shift towards collaboration.
