Reports from AFP
and BBC News
state that protesters have chanted slogans to denounce the military which has dissolved parliament and seized important legislative powers for itself.
The Muslim Brotherhood hold the majority of seats in parliament.
This current episode is being seen by many observers of the country's situation as another example of the bitter power struggle between the Supreme Council of the Armed Forces (SCAF) and the newly formed Morsi civilian government.
Mr. Morsi's lawyer Abdel Moneim Abdel Maqsud has stated the "ruling is null and void" and added that it constitutes a "political decision."
