Anti-Mubarak activists bruised, tired, hungry

After nearly two weeks of going head-to-head with Egypt's authoritarian regime, anti-government protesters are bruised, battered, sleep-deprived and hungry.

But the tens of thousands massing daily in Cairo's Tahrir Square remain fired with enthusiasm - at times a euphoric fervor seems their only fuel - and vow they will not back down in their demands for President Hosni Mubarak to step down and end his nearly 30-year rule. (AP)
