Once again, truce has been broken between protesters and security forces in the perimeter of the interior ministry in an episode of deadly clashes that has been going on since Thursday night.
A number of protesters reportedly started to advance and hurl stones towards police forces around the ministry gates. Shortly afterwards, a heavy round of teargas was fired by police forces pushing back the crowd.
State television's Nile News field reporters said the number of protesters increased reaching thousands in Mansour and Falaki streets, where the clashes have just been renewed, causing a stampede.
Teargas smoke hailed over the surrounding areas as ambulance vehicles started arriving to the two streets. Some protesters on motorcycles are also taking part in ferrying those who have suffocated or fainted to field hospitals.
Protesters marched on ministry streets Thursday night to blame the police for the deaths of Ultras fans, who have played a key role in the Egyptian revolution since 25 January, 2011, and many have been demanding the ruling military council step down.
73 football fans, mostly supporters of Ahly Ultras, were killed on Wednesday night after rival Masry fans stormed the pitch at the end of an Egyptian league game between Cairo's Ahly and Port Said's Masry.
According to the Egyptian ministry of health, the death toll in clashes that broke out on Thursday between thousands of protesters in a number of Egyptian cities, angry over the Port Said massacre on Wednesday, and police forces has risen to 12 by midday Saturday.
Five protesters were killed in Cairo, and seven in Suez.
More than 1500 people have been injured.
The game witnessed tensions from the starting minute and lacklustre security presence according to many eyewitnesses.
