evidence: Minutes after Iran’s Supreme Leader vowed ‘severe punishment’ to Israel in response to the assassination of Palestinian leader Ismail Haniyeh in Tehran on Wednesday, a symbolic red flag was raised over a major mosque in the holy city of Qom. [...] Iran has raised the red religious flag as a warning of a severe battle to come. [...] In ancient Iranian traditions, red flags were raised over the homes of those whose blood had been shed and were not lowered until vengeance was taken. In recent years, red flags have been raised during the processions of those killed "unjustly" and over the domes of mosques and shrines, as a sign of national mourning and a pledge of revenge.
