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.
