Cairo (CNN) -- A fire erupted at the entrance to Egypt's presidential palace Friday night as protesters hurled Molotov cocktails and rocks at security forces, who responded with tear gas and water cannon.
One person was fatally shot during clashes, according to an official from Cairo's Heliopolis Hospital, and authorities were seen dragging away demonstrators.
Egyptian television aired live footage of security forces beating a naked man on the ground. The Ministry of Interior said it would investigate the incident.
The nation has been rocked by violence since last week's second anniversary of its revolution. Protesters have fumed over the slow pace of change and recent edicts by President Mohammed Morsy, who imposed a 30-day curfew on areas engulfed by violence.
State TV reported that security forces were clearing the area in front of the palace as rioting continued.
