11:17 am: In today's session, three witnesses from Egypt's police are due to testify before the court - Sergeant Mohamed Abdel Hakeem Mohamed, Sergeant Abdel Hameed Rashed Abul Yazeed and former Major Tarek Abdel Moneim. Moneim has previously told the prosecutors that a police general and 15 of his aides broke into the building of the American University in Cairo, facing Tahrir Square, and opened fire against protesters from inside. 11:14 am: Al Jazeera's Mubashir Misr channel reports that Sameh Ashour, a former head of the bar association, and some of the lawyers representing victims' families have withdrawn from the hearings in objection to "chaotic" conditions inside the courtroom. 11:10 am: State TV reports that one of the plaintiff's lawyers insulted Mubarak during the hearings. 11:00 am: State TV says that the plaintiffs' lawyers demanded that Field Marshal Hussein Tantawi, former intelligence chief Omar Suleiman, and former First Lady Suzanne Mubarak be summoned to court to give their testimonies. Meanwhile, Mohamed Zahran, a relative of one of the protesters killed during the revolution, shouts at the anti-Mubarak protesters, demanding that they stop cursing and chanting anti-police slogans. “The media are deploying such acts to ridicule our cause and provide a legitimate pretext for the police to crackdown on us,” Zahran told Al-Masry Al-Youm outside the courtroom. State TV airs live footage from outside the courtroom with protesters raising banners that depict Mubarak's head surrounded by gallows. The banners read: "Put the serial killer on trial." 10:55 am: Al-Arabiya channel, quoting a source inside the courtroom, reports that Judge Ahmed Refaat refused to enter the courtroom because of lawyers chanting anti-Mubarak slogans in the courtroom. 10:52 am: State TV says the plaintiffs' lawyers are telling the court their demands. 10:40 am: A group of Ultras Ahlawy are playing with firearms and chanting anti-Mubarak slogans. Clashes erupted between the ardent football fans and security forces outside the Police Academy. No casualties have been reported so far. 10:30 am: Egypt's flagship paper Al-Ahram reported today that the Interior Ministry has decided to tighten its security measures around Gate 8 of the Police Academy. 10:29 am: State TV reports that five Kuwaiti lawyers are being seen inside the courthouse. 10:26 am: State TV reports that the trial has started. 10:28 am: Verbal clashes erupted in the courtroom between the defendants' lawyers and members of martyrs' families. Judge Ahmed Refaat, according to state TV, refused to enter the courtroom unless lawyers of both sides keep quiet. 10:00 am: Images from state TV show an ambulance carrying Mubarak stopping outside the courtroom, guarded by armed and masked army officers. Mubarak entered a room in the academy and a hospital bed was brought outside the room. Mubarak is seen laying on the bed and wearing a blue bathrobe. 9:55 am: A plane carrying Mubarak arrives at the Police Academy from the International Medical Center, where the former president is being hospitalized. 9:25 am: Some people are starting to gather around the Police Academy. Eyewitnesses said they are mainly anti-Mubarak protesters; their numbers are much fewer than the previous sessions. Rumors are circulating that a number of ardent football fans, known as the Ultras, may join the crowd to protest what they perceived as police brutality against their members on Tuesday night when Central Security forces chased Ahly fans outside the Cairo Stadium premises after they chanted slogans against Mubarak and Adly. 8:15 am: A team of five Kuwaiti lawyers, who previously announced that they will join the defense team of the ousted president, is being kept in a room close to the courtroom. No information is provided as to whether they will be allowed to enter the courtroom or not. 8: 00am: State TV reports that former Interior Minister Habib al-Adly and his six aides, along with Mubarak's sons, arrived at the Police Academy. 7:00 am: Trial of former President Hosni Mubarak is to convene for its fourth session Wednesday morning. Summary of the 5 August session: Four policemen took the stand Monday to supposedly testify against Mubarak and his top security officials. However, their testimonies fell short of proving that Mubarak and his notorious former Interior Minister Habib al-Adly did not order the use of weapons against protesters. The first witness General Hussein Saeed Mohamed Moussa, head of communications for Central Security Forces, said Ahmed Ramzy, former assistant minister for the Central Security Forces, was responsible for the order to arm Central Security Forces with automatic guns. The courtroom became chaotic after a pro-Mubarak lawyer raised the former president's photo, a move that infuriated the lawyers of the plaintiffs and members of the martyrs' families. Outside the court, scores of people were injured in clashes between Mubarak's supporters and anti-Mubarak protesters.
