Egypt crisis, and President mubarak.
Vigilante groups in Cairo have set up checkpoints amid reports of widespread looting. A BBC correspondent says the streets are on the brink of anarchy.
Mr Mubarak has appointed a vice-president as he struggles to regain control after five days of protests.
It is now believed at least 100 people have died since Tuesday.
The unrest in Egypt follows an uprising in Tunisia two weeks ago which toppled President Zine al-Abidine Ben Ali after 23 years in power.
The Tunisian upheaval began with anger over rising food prices, high unemployment and anger at official corruption – problems which have also left many people in Egypt feeling frustrated and resentful of their leadership.
