Pro-Morsi rally comes under fire in Cairo

At least one dead as unknown gunmen shoot at crowd in an apparent ambush of supporters of deposed president.

Supporters of deposed Egyptian president Mohamed Morsi were shot at by unknown gunmen in the early hours of Wednesday morning, witnesses said, in the latest of several violent incidents over the last 24 hours. The attack happened as a large group of pro-Morsi marchers made their way through the Heliopolis area in the north of Cairo, Al Jazeera's Rawya Rageh reported from the capital. "They say that they came under attack by unknown gunmen who shot at them from an elevated point," Rageh said. "They're reporting injuries among them. This again highlights the growing nature of intolerance towards those rallies of the Muslim Brotherhood and supporters of the deposed president." Footage from a field hospital in the Nasr City area showed at least one dead body. Several men, some covered in blood, were treated on hospital trollies as other men shouted and wept. A group of men gave one unconscious and bloodied protester CPR before doctors used a defibrillation machine to try to revive him. The attack came just 24 hours after the interior ministry said that at least twelve people were killed in clashes, also in Cairo, between supporters and opponents of Morsi. That violence broke out before dawn on Tuesday near a Muslim Brotherhood protest at Cairo University, where Morsi supporters have been camped out since the army removed him from power on July 3 after protests against his rule. There were also running street battles on Monday in which birdshot, gunfire and fire bombs were used. Anger and frustration Al Jazeera's Nicole Johnston, also reporting from Cairo, said the protesters were determined to stay in the streets and fight for their demands. "This isn't the first time that the pro-Morsi rally there has seen this kind of violence ... It's difficult to know how long the demonstrations and rally will continue," said Johnston. "We are talking about an angry, frustrated and determined crowd. If the interim government tries to send in forces [to disperse them], there could potentially be more bloodshed," our correspondent said. In a separate development, a bomb exploded at a police station in a province north of Cairo early on Wednesday, wounding 19 police officers, the Interior Ministry said in a statement. Reuters news agency said one person had been killed, citing security and medical sources. Rageh said the bomb detonated in an abandoned building near the police station in Mansoura, the capital of Dakhalia province. She said police then had a gun battle with a group of attackers. Adly Mansour, Egypt's interim president, has renewed appeals for reconciliation with Morsi's Muslim Brotherhood. "We want to turn a new page in the country’s book with no hatred, no malice, no division," he said in a pre-recorded speech that also highlighted the importance of the army in Egypt's history. About 100 people have died in violence since Morsi's removal.
