CAIRO: The cold weather in Tahrir Square forced the demonstrators to start a fire in the square for heating, which led to the rise of black smoke over the square. They also kicked out many cars from the square that had entered amid the state of calmness. Popular committees forced the drivers to leave the square. This happened during the late hours of the Friday of Revolution guardianship. Supporters of presidential hopeful Hazem Salah Abu Ismail called for this demonstration, but it did not meet any political or national flow. The popular committees centralized at the entrances and exits of the square, and the discussions continued about the military council and Prime Minister Kamal el-Ganzouri's government and its ability to implement the assigned duties.
