Supporters of Mohammed Morsi, Egypt's first elected president, demonstrated in Cairo's southern district of Maadi. Some held pictures of their fallen members. Others called for Morsi to be reinstated, urging military leader Gen. Abdel-Fattah el-Sisi to step aside.
Other scattered protests occurred across Egypt.
Morsi was overthrown along with his Muslim Brotherhood-led government in July 3 coup after millions protested against his leadership, claiming the Islamist president was incompetent and overstepped his authority during a year in power.
An umbrella group of Islamist parties, including the Brotherhood, said today's rallies were the beginning of a weeklong protest campaign until November 4 when Morsi is scheduled to appear in court. The campaign has been dubbed the week of "steadfastness."
Morsi faces criminal charges accusing him of inciting the murder of rallying opponents while he was in office.
