An Egyptian court sentenced 529 Muslim Brotherhood supporters with the death penalty on Monday of last week after a two day trial.
The security services are out to crush any resistance from supporters of the Brotherhood.
Students in Cairo struck last Sunday in protest at attacks on campus by the army.
The state has also targeted non-Brotherhood revolutionaries. High profile political blogger and activist Alaa Abdel-Fattah was released on bail last Sunday after over 110 days in detention. He and 25 other activists face charges of organising protests against military trials of civilians.
Meanwhile postal workers have rejoined strikes over pay and corrupt management this week against the background of deepening military repression. They had suspended their action, which started on 23 February, on 5 March after promises to address their demands.
But now the workers report 70-90 percent support for the strike, which is calling for a 50 percent pay rise, and the sacking of the Postal Authority president and his advisors.
Action by doctors, vets and medical workers over pay and services is continuing.
