Iran raised a symbolic red flag of revenge above an important mosque while vowing to take revenge against Israel over its assassination of Hamas Chief Ismail Haniyeh.

The red flag with the inscription, “O ye avengers of Hussein,” was raised above Jamkaran Mosque in the city of Qom. The flag is rarely raised outside the mourning of the Muharram month, which commemorates the death of the Shiite Imam Hussein ibn Ali. According to the Kashmir Observer, it has only been raised above the mosque outside of religious reasons six times in recent history, notably after the assassination of Islamic Revolutionary Guards Corps Leader Qasem Soleimani in January 2020.
