TEHRAN – A gunman armed with AK-47 assault rifle stormed the embassy of the Republic of Azerbaijan in Tehran on Friday morning, killing an Azeri national and injuring two others.

“We condemn the attack at the entrance of the embassy of our brotherly neighbor, the Republic of Azerbaijan,” Mohammad Jamshidi, a political aide to President Raisi, said in a post on his Twitter account.

He said Raisi “ordered a full investigation” into the issue and “expressed condolences to the govt, people & family of the murdered diplomat & prayed for the recovery of the injured.”

In his talks with Bayramov, Abdollahian also conveyed President Raisi’s grief to Azeri President Ilham Aliyev over the incident.

Condemning the attack, Abdollahian said the enemies are seeking to misuse the attack, suggesting “we should not allow this incident to leave negative impact on the relations between the two countries.”

Azerbaijan’s Foreign Ministry described the attack as "treacherous".

"An individual with a Kalashnikov rifle attacked the security post and killed the head of security. Two embassy guards were also wounded in preventing the attack. Their condition is satisfactory. This treacherous attack is currently under investigation. The public will be provided with additional information on the details," the ministry said, according to Azerbaijani media.

Meanwhile, Azerbaijan’s Foreign Ministry said it had summoned Iran’s Ambassador to Baku Abbas Mousavi in connection with what it called a terrorist attack against the embassy. During the meeting, the ministry said it was brought to the attention of the Iranian ambassador that the armed attack is strongly condemned.

It added that such attacks against diplomatic missions are unacceptable, and it is the duty of the receiving party to protect the building of the embassy from all kinds of attacks and ensure the safety of its employees, based on the “Vienna Convention on Diplomatic Relations.”

President Aliyev called the assault a “terrorist act” and demanded a swift investigation.

In a statement, Aliyev said, “We demand that this terrorist act be investigated and the terrorist be punished.” He said an attack against a diplomatic mission was “unacceptable.”

Azerbaijan also evacuated staff from its embassy in Tehran, blaming Iran for the attack, Press TV reported.
