DUBAI, United Arab Emirates—Gunmen attacked a major Shiite mosque in Iran on Wednesday, killing at least 15 people and wounding dozens. The attack came as protesters elsewhere in Iran marked a symbolic 40 days since a woman’s death in custody ignited the biggest anti-government movement in over a decade.
State TV blamed the attack on “takfiris,” a term that refers to Sunni Muslim extremists who have targeted the country’s Shiite majority in the past. The attack appeared to be unrelated to the demonstrations.
The official website of the judiciary said two gunmen were arrested and a third is on the run after the attack on the Shah Cheragh mosque in Iran. The state-run IRNA news agency reported the death toll and state TV said 40 people were wounded.
An Iranian news website considered to be close to the Supreme National Security Council reported that the attackers were foreign nationals, without elaborating.
Such attacks are rare in Iran, but last April, an assailant stabbed two clerics to death at the Imam Reza shrine, the country’s most revered Shiite site, in the northeast city of Mashhad.
Earlier on Wednesday, thousands of protesters had poured into the streets of a northwestern city to mark the watershed 40 days since the death in custody of 22-year-old Mahsa Amini, whose tragedy sparked the protests.
Deaths are commemorated in Shiite Islam—as in many other traditions—again 40 days later, typically with an outpouring of grief. In Amini’s Kurdish hometown of Saqez, the birthplace of the nationwide unrest now roiling Iran, crowds snaked through the local cemetery and thronged her grave.
“Death to the dictator!” protesters cried, according to video footage that corresponds with known features of the city and Aichi Cemetery. Women ripped off their headscarves, or hijabs, and waved them above their heads. Other videos showed a massive procession making its way along a highway and through a dusty field toward Amini’s grave. There were reports of road closures in the area.
State-linked media reported 10,000 protesters in the procession to her grave.
Hengaw, a Kurdish human rights group, said security forces fired tear gas to disperse demonstrators. The semiofficial ISNA news agency said security forces fired pellets at crowds of demonstrators on the outskirts of Saqez and pushed back demonstrators who tried to attack the governor’s office. It said local internet access was cut off due to “security considerations.”
