Demand for change rocks Arab world Protests continue to shake the Middle East and North Africa as thousands rally against autocratic regimes that have held power for years, if not decades.

Protests in Egypt have led to clashes with security forces, leaving at least six people dead and hundreds wounded. Nearly 1,000 people are known to have been detained so far.
