As many as 20 supporters of the Muslim Brotherhood were arrested in Alexandria amid Friday's protests.
Meantime, two blasts occurred Friday in districts of al-Agami and el-Wardian, west of Alexandria, resulting in the injury of a police officer and a driver.
In December 2013, an Egyptian court labelled the MB group a terrorist organization, blaming it for a string of attacks in the country and banning all its activities nationwide.
