Hundreds of supporters and opponents of Egypt's ousted dictator, Hosni Mubarak, have clashed outside a court in Cairo where he is being tried on charges related to the killing of protesters during the North African country’s 2011 revolution.

The Egyptian security sources say several protesters were wounded during the violence that erupted when the court's judge adjourned the trial of Mubarak and his two sons until Oct. 19.

Among the wounded were families of the victims who were killed during the revolution in Egypt.

Medics say most of the injured were treated outside the courtroom and those with more serious wounds were taken to nearby hospitals.

Scuffles also took place between supporters and opponents of Mubarak who were watching the court proceedings on large screens across the volatile city.

Egyptians are anxiously following Mubarak's trial across the country. People have gathered in Cairo's shops and cafes to watch the trial on television.

The court has now ordered ban on airing the next hearings of the retrial.

Mubarak was convicted and sentenced to life in prison for failing to stop the killings during the 2011 revolution. But his sentence was overturned on appeal earlier this year and a retrial was ordered.

He has been held at the military hospital since his release from Cairo's prison last month.

Mubarak's case threatens to increase tensions across the North African country. The country plunged into turmoil after the army overthrew former president, Mohamed Morsi on July 3.

Some Egyptians are accusing the military-backed court of seeking to acquit the former dictator.
