Thousands of Egyptians on Tuesday rallied in front of the presidential palace to protest recent presidential decrees and a fresh draft constitution. Some 18 political parties and revolutionary groups camped at Tahrir Square, have announced they will join a mass peaceful march to the palace. Security forces used tear-gas to disperse the protesters and keep them away from the barriers at the presidential palace. Hundreds of black-clad riot police were deployed around the Itihadiya Palace in Cairo\'s district of Heliopolis. Barbed wire was also placed outside the complex, and side roads leading to it were blocked to traffic. The march, called the \"Final Warning\" comes amid rising anger over the draft constitution and decrees issued by President Mohammad Morsi giving himself sweeping powers. Morsi called for a nationwide referendum on the draft constitution on December 15. Meanwhile, thousands of protesters gathered in Cairo\'s Tahrir Square, joining several hundreds who have been camping out there for nearly two weeks. There were other protests around the city. The irate demonstrators came from several squares and centers in Cairo to join the mass march. They chanted slogans against the Egyptian leader, calling for him to scrap his recent controversial constitutional edicts.
