Egypt unrest: Concerns over freedom of the media

Rival rallies are expected in Cairo on Friday amid rising tensions over the army's overthrow of Islamist President Mohammed Morsi last week.

On Thursday, the Obama administration and UN both raised concerns about Egypt's decision to issue arrest warrants for the leader of the Muslim Brotherhood and nine senior figures of the movement.

There have been hundreds of arrests and there are widespread allegations of the torture of detainees.

Now some Egyptians are asking whether their hard-won freedom of the media and of expression are at risk, as Andrew Hosken reports from Cairo.
