Egyptian Nobel Laureate Mohamed ElBaradei returns home to assume opposition leadership role

Egypt's most prominent democracy advocate took up a bullhorn Sunday and called for President Hosni Mubarak to resign, speaking to thousands of protesters who defied a curfew for a third night.

Fighter jets streaked low overhead and police returned to the capital's streets -- high-profile displays of authority over a situation spiraling out of control.

The Egyptian opposition leader, Mohamed ElBaradei, tonight predicted change within "the next few days" as western leaders pointedly declined to throw their support behind the country's embattled president, Hosni Mubarak.

In another dramatic day, thousands of protesters kept up the pressure on a defiant Mubarak amid sporadic violence and signs that the US and allies may ditch him unless he allows an "orderly transition".
