The Egyptian military swept into Cairo’s Tahrir Square in an attempt to end a fifth day of clashes between protesters and police. The military sent armored cars and troops into the square in an attempt to separate the two sides, but soon demonstrators and police resumed throwing rocks and firing tear gas at one another. The Egyptian government earlier claimed that a truce between protesters and police had been reached. Officials say the death toll for the last five days has risen to 38. As the sixth day begins, demonstrators are calling for the military government to hand over power and Field Marshal Mohamed Hussein Tantawi to resign. The U.N. has called for an investigation into the crackdown.
