CAIRO (AFP) - A large group of Egyptians rallying for reforms branched off from a protest in Cairo's Tahrir Square and attacked Israel's embassy on Friday, destroying a protective wall with sledge-hammers. Thousands of protesters massed in Tahrir Square, the epicentre of an uprising that ousted president Hosni Mubarak in February, to demand reforms and an end to military trials of civilians. The protesters, who had gathered under a scorching sun, filled a section of the square to listen to Juma prayer sermon. "It would be shame on the Egyptian people if they forget their revolution," the preacher said. He criticised some of the prosecution witnesses in the ongoing murder trial of Mubarak and his security chiefs for testifying this week that they had not been ordered to use deadly force against protesters during the revolt. "They must be charged with false testimony. How can a prosecution witness turn into a defence witness?" the cleric asked. The preacher also denounced military trials for civilians.
