Egypt's authorities raised the security alert in the different governorates to confront the calls adopted by the Muslim Brotherhood (MB) for demonstrations, Youm7 reported. The banned group called its supporters for rallying in the streets on Friday to express their protest against the death sentences issued against former President Mohamed Morsi and other MB leaders. The authorities are scheduled to push military forces to secure the different institutions and to counter any attempts to target the state institutions. The security forces will intensify their presence in the metro and railway stations and public transportations to prevent any potential attacks. A security source said to Youm7 on Friday that the Egyptian security is prepared for dealing with any attempts to raise the chaos or to destabilize the country
