Adil Abdul Mahdi have accused the Iraqi protesters of using the Mangonel (Arabic منجنيق ) The mangonel, also called the traction trebuchet, was a type of trebuchet or siege engine used in Ancient China starting from the Warring States period, and later across Eurasia in the 6th century AD.
The protesters have mocked him since they have renamed the Turkish Restaurant Building in Tahrir Square into Mount Uhud (Arabic: جبل احد) Mount Uhud is a mountain north of Medina, Saudi Arabia. It is 1,077 m high. It was the site of the second battle between Muslim and Meccan forces. The Battle of Uhud was fought on 19 March, 625 CE, between a force from the small Muslim community of Medina, in what is now north-western Arabia, and a force from Mecca.
Uhud Mount became the most symbolic sign of the Iraqi revolution
