evidence: A blood-red flag symbolizing vengeance unfurled Saturday above the dome of Jamarkaran Mosque in Qom, Iran, a day after the United States killed Iranian Gen. Qassem Soleimani and Iraqi militia leader Abu Mahdi al Muhandis. [...] Very very unusual to see a red flag flying over holy mosque of Jamkaran in Qom, Iran‘s holiest city. It’s is almost always blue. The red flag symbolises revenge. pic.twitter.com/0VeWvUY37L — Ali Arouzi (@aliarouzi) January 4, 2020 [...] Jamarkaran Mosque is one of the holiest sites in Shiite Islam and one of the mosques associated with the Mahdi, also known as the 12th Imam. Some Muslims believe the Mahdi is alive but hidden and will emerge to rule the world shortly before the Day of Judgment. Referencing the Mahdi, the speaker called, "O Allah, hasten your custodian reappearance," as the flag was raised.
