Opponents and supporters of Egypt's deposed president, Mohamed Morsi, clashed in the Mediterranean city of Alexandria on Wednesday after the army announced his removal from office.
Gunfire was heard as rocks and bricks flew, said witnesses.
“We are dealing with the situation … We have called for security reinforcements in the area,” said senior police officer Sherif Abdelhamid.
