Army and police forces marched into Cairo's Tahrir Square Sunday spraying tear gas in an attempt to clear protestors.
Four people died in the square as police were seen beating and arresting people reported http://www.cnn.com/2011/11/20/world/africa/egypt-protests/index.html?hpt=wo_c2.
The protesters are out in the streets and upset about the military. They are demanding that the military "announce a date for the handover of power to a civilian government" reports MSNBC.com.
They have been throwing Molotov cocktails, rocks and setting fire to police vehicles. At least 1,114 people have been injured.
