Cairo courthouse bombed as Egypt referendum begins

A small bomb has been detonated outside a courthouse in the Egyptian capital, Cairo, as two days of voting in a referendum on a new constitution begins.

No casualties have been reported as a result of the explosion, which happened in the Imbaba district.

James Reynolds, reporting from Cairo, says it is thought the building was being used as a base to monitor the referendum.
