Blood on Bernanke's Hands; Riots in Egypt over Food Prices and Unemployment; Protests Spread to Algeria, Morocco and Yemen; Twitter in the Spotlight

Violence in Egypt continues unabated in spite of President Hosni Mubarak's plea for calm. Demonstrators threw firebombs and chanted "Down with Hosni Mubarak, down with the tyrant." Police responded with teargas and bullets.

Protesters are angry over poverty, rising food prices, state food subsidies, unemployment, and social conditions.

Social media outlets, especially Twitter have played a leading role in organizing protests. The Obama administration and the US state department have also resorted to Twitter and Facebook.
