Two years after the ouster of former Egyptian President Hosni Mubarak, protesters clashed with police Monday at the presidential palace - this time against the policies of his elected successor Mohamed Morsi.
In other demonstrations, hundreds of policemen also took to the streets. They're demanding they not be used as a tool for political oppression in the country's ongoing turmoil.
The rallies reflect fears among many policemen of a public backlash, after weeks of violent crackdowns on anti-government protests.
Cairo's Tahrir Square is still a focus of many protests, but recently it's become notorious for more menacing reasons: the number of sexual assaults that take place there.
