The Egyptian Revolution of 2011. began on 25 January 2011 and was part of the Arab Spring. It consisted of demonstrations, marches, occupations of plazas, riots, non-violent civil resistance, acts of civil disobedience and strikes. Millions of protesters from a range of socio-economic and religious backgrounds demanded the overthrow of Egyptian President Hosni Mubarak. The revolution included Islamic, liberal, anti-capitalist, nationalist and feminist elements. Violent clashes between security forces and protesters resulted in at least 846 people killed and over 6,000 injured. Protesters burned over 90 police stations.The protests took place in Cairo, Alexandria and other cities..During the uprising the capital, Cairo, was described as "a war zone" and the port city of Suez saw frequent violent clashes. Protesters defied a government-imposed curfew, which was unenforced by the police and military. Egypt's Central Security Forces police, loyal to Mubarak, was gradually replaced by military troops. In the chaos, there was looting by gangs which was instigated (according to opposition sources) by plainclothes police officers. In response, watch groups were organized by civilians to protect neighbourhoods..On 11 February 2011 Vice President Omar Suleiman announced that Mubarak would resign as president, turning power over to the Supreme Council of the Armed Forces (SCAF).
