Protests become increasingly violent, including attacks on reporters and human rights activists

Menacing gangs backing President Hosni Mubarak attacked journalists and human rights activists Thursday in an ugly turn in Egypt's crisis as government opponents pushed supporters out of Cairo's main square in a second day of battles.

Organizers called for protesters trying to topple the regime to fill every square in the huge capital on Friday.

Protesters and regime supporters skirmished in a second day of rock-throwing battles at a central Cairo square while new lawlessness spread around the city. New looting and arson erupted, and gangs of thugs supporting President Hosni Mubarak attacked reporters, foreigners and rights workers while the army rounded up foreign journalists.

Egyptian President Hosni Mubarak, who earlier reshuffled his political leadership and promised reforms in an unsuccessful attempt to mollify the protesters, also has said he won’t stand for re-election next fall.

Not good enough, say the demonstrators. They want Mubarak out now.
