At least nine people are dead in Egypt after supporters of ousted president Mohamed Morsi clashed with security forces Tuesday on the first day of a key vote on a new constitution.
The military-backed interim government wants the new charter to replace the constitution passed while Morsi was in power.
The military is hoping to get strong backing for the charter to validate its removal of Morsi.
A strong 'Yes' vote on a new constitution could also pave the way for fresh elections.
Despite tight security for the two-day vote, five people were killed in clashes in and around Cairo.
Four people were killed and more wounded in Sohag, though details of the incident are disputed.
Even before the voting began, a bomb exploded near a courthouse in Cairo, but no one was hurt.
