Via the BBC: Egypt protesters attacked by ‘armed civilians’ in Cairo
On Sunday, men in plain clothes armed with swords and petrol bombs confronted the pro-democracy activists after soldiers dispersed a Cairo rally they were holding to demand reform of the security services, eyewitnesses say.
"The army started firing in the air to disperse us," Mohammed Fahmy told Reuters news agency.
"We tried to run away but we were met by 200 thugs in plain clothes carrying sharp weapons."
Mr Fahmy put the number of protesters at 2,000.
