In an ominous warning, the head of Egypt's armed forces has said that continuing civil unrest may soon cause the collapse of the Egyptian state. Parts of Egypt are in turmoil following five days of rioting in which 52 people have been killed and more than 1,000 injured after protests against President Mohamed Morsi, the Muslim Brotherhood and police brutality turned violent. The unrest comes two years after the start of the 2011 revolution that toppled the former dictator Hosni Mubarak.
