Egyptian constitution: emerging split in society

There were clashes in the Egyptian city of Alexandria on the eve of the second leg of voting in the country's constitutional referendum.
Police fired tear gas as thousands of Islamists were met by a smaller group of protesters near a large mosque.
The Islamists back President Mohammed Morsi and his draft constitution. Opponents say the document has been rushed and does not protect minorities.
Before the first round of voting, some of the worst violence was in the nearby industrial city of Mahalla, in the Nile Delta. From there, Shaimaa Khalil reports on an emerging split within Egyptian society.
