The Associated Press reports:
Egyptian troops opened fire on mostly Islamist protesters marching on a Republican Guard headquarters Friday to demand the restoration of ousted President Mohammed Morsi, killing at least one. The shooting came as tens of thousands of his supporters chanting "down with military rule" rallied around the country.
The shooting came when hundreds of Morsi supporters marched on the Guard building, where Morsi was staying at the time of his ouster before being taken into military custody in an unknown location. The crowd approached a barbed wire barrier where troops were standing guard around the building.
When one supporter hung a sign of Morsi on the barrier, the troops tore it down and told the crowd to stay back. A protester hung a second sign and the soldiers opened fire on the crowd, an Associated Press photographer at the scene said. Several protesters were wounded, many with the pockmark wounds typical of birdshot.
