One man was killed in clashes
between security forces and supporters of ousted President
Mohamed Mursi's Muslim Brotherhood
on Tuesday, the first day of
a constitutional referendum, security sources said.
Mahmoud Sayed Gomaa, 25, was killed during a protest against
the referendum near a polling station in the province of Bani
Suef, south of Cairo.
The referendum is the first ballot since the military
overthrew Mursi on July 3 after mass protests against his rule.
