Armoured vehicles in Cairo's Tahrir Square on Friday

Armoured vehicles in Cairo\'s Tahrir Square on Friday Cairo – Al-Deeb Abu Ali At least 75 supporters of ousted Egyptian president Mohamed Morsi were killed in clashes with police in Cairo early on Saturday, doctors at an Islamist-organised field hospital said.
Another 1,000 people were wounded in the violence on the road to Cairo airport, said the medics at the hospital set up by Morsi\'s supporters at their protest camp in the nearby Nasr City district.
The Muslim Brotherhood\'s Murad Mohammed Ali told AFP that police had fired live rounds at Islamist demonstrators but the state MENA news agency cited a security official it did not identify as denying any live fire by police.
Clashes broke out at dawn on the road to the airport, with police firing tear gas at stone-throwing protesters, the state MENA news agency said.
It reported that buckshot was fired but said it was unclear who had fired it.
It came as Egypt’s Interior Ministry released a press statement denying security forces had turned their guns on protestors, saying firearms had not been used when it intervened to break up clashes between Morsi-supporters from the Rabaa el-Adaweya and residents on Nasr Road.
The statement added that security forces had used teargas to disperse demonstrators from Rabaa el-Adaweya after they attacked security personnel using stones and birdshots.
It said eight members of the security forces had been injured in the clashes.
It also came as authorities charged the ousted president with murder and formally remanded him in custody for 15 days. He had been held without charge since hours after his ouster by the army on July 3.
Morsi stands accused of the \"premeditated murder of some prisoners, officers and soldiers\" when he broke out of prison during the 2011 uprising that toppled veteran strongman Hosni Mubarak, MENA said.
The charges came as hundreds of thousands of supporters and opponents of the July 3 coup took to the streets on Friday, sparking fierce clashes in the Mediterranean city of Alexandria that left seven people dead.
Army chief General Abdel Fattah al-Sisi, who orchestrated the coup, had called on Wednesday for a mass show of support for a crackdown on \"terrorism.\"
