CAIRO, Nov 6 (Reuters) - Egypt's Muslim Brotherhood lost an appeal on Wednesday against a court decision to ban the group and seize its funds, court sources said.

A court in September banned the Brotherhood, Egypt's oldest and most influential Islamist group, after Islamist president Mohamed Mursi was ousted by the army following mass protests against his rule on July 3. (Reporting by Hadeel Al-Shalchi; Editing by Yara Bayoumy)
