CAIRO: There is an intensified presence of security forces in Tahrir Square. They surrounded the square in anticipation of potential demonstrations after Friday prayers. There are 18 armed vehicles full of security troops who are deployed at the entrances and exits of square. However, the number of military troops decreased in certain places leading to the square. Deploying the security troops is in framework of securing a plan to prevent any mobs since a group of youth tried to break into the square to take control over it again. The police and military troops broke up the mob and regained control.
