Inside an Egyptian polling station

As Egyptians go to the polls to vote on a referendum over a possible new constitution, the BBC's Sally Nabil explains the process involved.

Although the ballot is a simple yes/no affair, security is high. Voters must get their fingers inked to ensure they cannot vote more than once.

The military wants a strong "Yes" vote to endorse the removal of former President Morsi last year, and the government has used a new anti-protest law to silence the "No" campaign.
