Al-Jazeera Video: Protesters clash with police in Cairo

"Egyptian protesters set cars alight and threw stones at military police in Cairo, after rumours spread that an activist had been detained at a sit-in and badly beaten near the parliamentary building.

Police fired in the air shortly after dawn on Friday to try to disperse around 300 demonstrators, who were angered by images posted online that appeared to show the activist badly beaten after his arrest, witnesses told the Reuters news agency.
