Anger of protesters in Cairo 'surprised police'
Police in Cairo have been using tear gas and water cannon to try to quell rare anti-government protests.
Thousands have joined the protests after an internet campaign inspired by the uprising in Tunisia.
They marched through Cairo and other areas chanting anti-government slogans, after activists called for a "day of revolt" in a web message.
The BBC's Jon Leyne has been watching events unfold and said the "energy and anger" of the protesters took police in the Egyptian capital by surprise.
The mobile phone footage in this video was sent in to the BBC by members of the public in Cairo.
