At least two people were killed and 260 injured in the Egyptian Delta town of Mansoura Thursday night where the first disturbances took place ahead of the mass opposition rally called Sunday to overthrow Muslim Brotherhood government rule. There were also clashes in Tanta, Egypt’s third largest city, between supporters and opponents of President Mohamed Morsi. Army units have taken up positions around the main cities, especially Cairo. Morsi tried to calm the unrest by admitting in a speech to the nation Thursday that he made some mistakes in his first year in power but also achievements. He accused opposition forces of conspiring to overthrow him while threatening democracy, polarizing the nation and plunging Egypt into chaos. The opposition Salvation Committee responded that the president is in need of a first class psychologist.
