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.
