A person was killed and eight others were injured in an armed attack on Sunday targeting a Shiite shrine in the city of Shiraz in southern Iran, according to reports by the official news agency "IRNA" citing officials, marking the second such attack on the same shrine in less than a year.

IRNA quoted Esmail Ghazal Sofla, the deputy governor of Fars, stating, "A person was killed and eight others were injured in the attack."

He also added that the injured "were transferred to medical centers and are receiving treatment."

No group has claimed responsibility for the attack as of now.

Initially, the casualty count in Iranian media varied, with IRNA and the "Tasnim" news agency reporting that the attack was carried out by two gunmen, one of whom was apprehended while the other fled.

However, the commander of the Revolutionary Guard in Fars province, Yadollah Bouali, told state television that the attack was conducted by a single individual who was arrested.

Bouali added, "A terrorist entered the shrine and opened fire with a rifle."

He also clarified that "many visitors who were nearby sustained injuries."

Footage broadcast by state television showed ambulances rushing to the site of the attack.

IRNA reported President Ebrahim Raisi's statement that he ordered an investigation into the attack, promising to bring those responsible to justice.

Second attack:

This is the second attack targeting the shrine of Ahmad ibn Musa al-Kadhim, the brother of the eighth infallible imam in Twelver Shiism, Imam Reza, in less than a year. This shrine is considered one of the most important Shiite pilgrimage sites in the Islamic Republic.

In October 2022, 13 people were killed and 30 others were injured in an armed attack on the same shrine. At that time, the Islamic State jihadist group claimed responsibility for the attack.

Last July, the "Mizan Online" website affiliated with the Iranian judiciary reported that two men were hanged in a public square for their involvement in the attack on the shrine in Shiraz.

The website stated that Mohammad Ramez Rashidi and Naeem Hashim Qutali were executed after being convicted of charges of "corruption on earth, armed rebellion, and acting against national security," in addition to "conspiring against the security of the country."

The website did not specify the nationality of these two men, although authorities stated following the attack that foreigners of various nationalities, including Afghans, were involved in the attack.

In November, the Islamic Republic announced the arrest of 26 "Takfiri terrorists" from Afghanistan, Azerbaijan, and Tajikistan for their links to the attack.

"Takfiri terrorists":

In Iran, where the majority of the population adheres to Shiite Islam, the term "Takfiri terrorists" is commonly used to refer to jihadists or individuals from extremist Sunni organizations.

Last month, IRNA reported that those convicted in the shrine attack were hanged on the morning of July 8 in a street near the shrine located in Shiraz, the capital of Fars province.

According to "Mizan Online," Rashidi admitted to cooperating with the terrorist organization ISIS to carry out the shootings.

For his part, Kazem Mousavi, the chief justice of Fars province, confirmed that three other defendants in this case were sentenced to prison terms of 5, 15, and 25 years after being found guilty of belonging to the Islamic State organization.

According to Iranian authorities, the main attacker, described by Iranian media as a man in his thirties named Hamid Bodkhshan, died from injuries sustained during his arrest.

Shortly after the attack, in November, Tehran announced that 26 "Takfiri terrorists" from Afghanistan, Azerbaijan, and Tajikistan were arrested for their links to the attack.

The first attack claimed by ISIS in Iran dates back to 2017 when gunmen and suicide bombers attacked the parliament building in Tehran and the shrine of Ayatollah Ruhollah Khomeini, the founder of the Islamic Republic, resulting in 17 deaths and dozens of injuries.

The attack on the Shah Cheragh shrine last year came more than a month after massive protests erupted in Iran following the death of a young Kurdish Iranian woman while in custody.

Mahsa Amini, 22, died three days after being detained by the morality police for allegedly failing to comply with the strict dress codes imposed on women in the Islamic Republic.

At that time, Raisi stated that the "riots," a term used by authorities to describe the protest demonstrations, paved the way for "terrorist" attacks.
