Egyptian Military Opens Fire on Pro-Morsi Rally in Cairo, At Least One Supporter Dead (VIDEO)

At least one of Morsi's supporters was shot dead by security forces as they opened fire on a rally outside the building where the former President of Egypt is allegedly being detained.

The chaotic scene at Republican Guard headquarters made it difficult to report the exact number of casualties, the Washington Post reported on Friday. But witnesses claimed that a handful of people gathered at the pro-Morsi rally sustained injuries. Some local media outlets said that more than one person died once the army opened fire on the crowds.

According to Al Jazeera, more than three supporters of Morsi died once the Egyptian army began shooting into a crowd of several hundred, in addition to a few dozen people who were hurt by shotgun pellets.

"One protester broke away from the rally to stick a pro-Morsi poster on the barbed-wire around the barracks," Al Jazeera's Matthew Cassel said, reporting from Cairo. "He was shot in the head with birdshot."

One of the organizers of the demonstration, Muslim Brotherhood-affiliated Freedom and Justice Party, released a statement saying that five people at the protest were killed.

According to the Washington Post, this violence only added to mounting worry that Morsi's primarily Islamist support foundation and their adversary, Egypt's security forces, might turn into all-out warfare.

Helicopters buzzed above the headquarters, observing the masses of people that streamed into the area outside Rabaa al-Adawiya Mosque.

One of the speakers at a Friday evening prayer service held earlier in the day was the Muslim Brotherhood's "supreme guide," Mohammed Badie. He swore that Egypt's Islamic population would fight to take back their rights.

"Free revolutionaries, we will continue the path," they chanted, as the Associated Press reported from Egypt.

Badie currently has a warrant out for his arrest which has been issued by the Egyptian army.

A different speaker approached the podium, and in his speech, said that Morsi's coerced ousting was an attack on the Egyptian population's character.

"There are Americans and Zionists behind this," the speaker stated, referring to claims that the United States government gives massive financial aid to the Egyptian army, in addition to training some of the soldiers within American borders.
