Egypt has been plunged into further turmoil with the military accused of "massacring" Islamist protesters in Cairo.
The protesters, believing ousted President Mohammed Morsi is being held in the barracks, protested outside. The military says it came under attack from "terrorists" shortly before dawn, while the demonstrators maintain soldiers opened fire upon them "indiscriminately" during morning prayers.
At least 42 people were killed and over 300 wounded.
The Muslim Brotherhood says many of the injured have been denied access to makeshift hospitals set up in the Nasr City district while doctors have described the scene as a "warzone".
Muslim Brotherhood calls for another uprising
The political fallout has been immediate with the Al Nour Islamist movement pulling out of negotiations with the interim government.
The Muslim Brotherhood has held a press conference in Cairo, accusing the army of a massacre and calling for the people of Egypt to "rise up" against the military.
On the other side, Mohamed El Baradei, nominated as interim Prime Minister, has tweeted calling for an independent investigation and condemned the shootings.
Violence begets violence and should be strongly condemned. Independent Investigation a must. Peaceful transition is only way .

Meanwhile, the Tamarrod protest movement, very much at the centre of the anti-Morsi demonstrations, has called on the Muslim Brotherhood to be banned.

Meanwhile, the European Union says it's "strongly concerned" by the violence but says there are no plans to review the aid it sends to Egypt.
The Obama adminstration, which hasn't been in a position to answer questions on the military upheaval since Morsi was overthrown because of the 4th of July holiday, is expected to face questions about its $1.5 billion aid package to Egypt. Most of that money goes directly to the country's military.
