The protest against repression in Iran continued, with a dramatic gesture. The photographs are striking. If you can open the link in The Washington Post, I think you will agree.

As Iranian protests sparked by the death of a woman in police custody continued, several Tehran fountains on Friday appeared as if filled with blood, according to photos and a video — verified by Storyful — that were shared widely on social media. The Persian-language Twitter account 1500tasvir, which has been monitoring the state crackdown that has killed dozens, credited the red liquid in the fountains’ basins to an anonymous artist/activist, referring to it as a protest artwork whose title roughly translates to “Tehran sinking in blood.”

The affected fountains are in culturally significant locations, including one in Daneshjoo Park, near the City Theater, which has been the subject of government censorship, and another in front of the Iranian Artists Forum, an interdisciplinary arts space founded during the reform-oriented presidency of Mohammad Khatami.

According to the Voice of America, citing the BBC’s Persian service, the fountains have since been drained. But for a moment, the ephemeral work served as a visceral reminder of the sacrifices made in the name of women’s rights.

Iran’s weeks-long protests began in mid-September, after Mahsa Amini, 22, was arrested by the “morality police” for allegedly wearing a hijab incorrectly, and died in custody. The death has fueled sprawling protests. Schoolgirls have removed their head coverings and raised middle fingers. Women have burned their hijabs and cut their hair. People have flooded the streets chanting, “Women, life, freedom” and “Death to dictator,” a reference to Iran’s supreme leader, Ayatollah Ali Khamenei.
