At least 50 people were killed and more than 300 injured Monday in clashes outside a military building in Cairo, according to an Egyptian Health Ministry spokesperson.
Ministry spokesman Khaled el-Khatib said initial reports also indicated at least 322 were wounded, although he gave no details on the circumstances of the killings.
Witnesses tell Fox News that Muslim Brotherhood supporters were fired upon with birdshot and rounds from automatic weapons at around 5:30 a.m. local time, during morning prayers. Fox News sources who were at the scene shortly after the shooting described seeing Muslim Brotherhood supporters with large chest wounds and fatal gunshot wounds in their backs.
The Muslim Brotherhood have blamed the attacks on the Egyptian military troops, who were standing guard over the demonstration near to the Raba El Adwyia mosque.
