Clashes between Egyptian security forces and protesters in central Cairo have left 26 people injured, state media reported Wednesday.
The clashes, the worst confrontation between state security forces and protesters since the country's January 25 revolution, which led to the fall of president Hosny Mubarak, began on Tuesday night, DPA reported.
Hundreds of relatives of those who died in the protests gathered on Tahrir Square to protest what they regard as the military caretaker government's failure to bring those responsible to justice.
Police used tear gas in a bid to disperse the crowd, resulting in overnight street battles and a stand-off with protesters armed with rocks.
Early Wednesday, the clashes continued, with the number of protesters swelling as activists pressing for change in the country streamed to the square.
Some of the protesters were chanting slogans calling for the resignation of the head of the military Field Marshal Mohammed Hussein Tantawi.
