The turmoil in Egypt continued overnight on Friday and into Saturday as more people were injured and killed in ongoing protests. Doctors in Cairo say over 100 protesters supporting ousted President Morsi were killed in the city and that over 1,500 were hurt. The state health ministry disputes the numbers, putting the death toll at 38. Protests were held by both sides overnight, with the anti-Morsi side in Tahrir Square and tens of thousands of pro-Morsi activists staging a sit-in at a mosque. The interior minister vowed to end the protests on Saturday through legal means, although nothing has happened as yet.
"It appears that clashes began after some of the Morsi supporters tried to block a main road in the area, and security forces responded.
The state news agency Mena quotes a security official as saying they had been trying to stop fighting between rival sides, and that eight security personnel had been injured.
The official added that live fire had not been used, only tear gas.
But our correspondent says medics at the hospital believed about 70% of the casualties were caused by live fire - with many of the victims hit in the chest or head by snipers firing from rooftops.
Ahmed Nashar, a Brotherhood spokesman witnessed what happened near the Nasr City mosque where demonstrators built a wall to protect themselves.
"When I arrived, bullets were whizzing past my ears," he told the BBC. "Today was just brutal - people were fired at, with live firearms."
Our correspondent says Morsi supporters are furious about the role the military is taking, and in particular the head of the army, General Abdel Fattah al-Sisi, whom they say is killing Egyptians."
