Darkness fell and Port Said was shaken by another night of violence. Protestors hurled petrol bombs and stones at police officers who, they say, responded by firing tear gas and rubber bullets.
The Egyptian state news agency says 35 people have been injured and taken to hospital.
Earlier, people gathered outside the local government offices to protest against the ongoing detentions. The nearby headquarters of the security services was set on fire.
“We had never the intention to do anything to them”, said one man. “It was them who beat us.Violence was provoked each time by agents of the interior ministery, or police or a third party, or I don’t know who started beating us.”
Demonstrators were on their way back from the funeral of one of those killed at the weekend when their grief turned into anger.
There are those here who blame the police for deaths and injuries, claiming they use excessive force.
