More than 20 youth activists will go on trial on Sunday for taking part in an illegal protest, including the sister of a prominent figure from the 2011 uprising recently jailed over similar charges. After the army ousted Islamist president Mohamed Morsi last July, the authorities launched a harsh *****down on the Islamist and secular opposition. In recent months, dozens of youth activists have been jailed for protesting illegally, after a law banning all but police-sanctioned rallies was adopted in **vember. They are charged with "protesting without authorisation, damaging public and private properties and blocking traffic," defence lawyer Mohamed Abdel Aziz told AFP.
