Crisis in Egypt - James A. Baker III on Middle East Political Change

Thousands of Egyptians have taken to the streets in Cairo, Alexandria and across the country, calling for the ouster of Egyptian President Hosni Mubarak.

The Egyptian military and police have been battling protesters with tear gas and rubber bullets, and the government has cut off access to the Internet, mobile phones and curtailed social media.

The riots follow a similar uprising in Tunisia that prompted the country's long-time president and dictator, Zine el-Abidine Ben Ali, to flee.
