CAIRO - About 15 people were injured during clashes Friday between Egypt’s military and supporters of Mohammed Morsi outside the barracks where the ousted Islamist president is believed to be detained.
Some of the wounded being treated near the scene appeared to have been hit by shotgun fire. NBC News journalists saw people with injuries to their face and torso.
The violence broke out after about 6,000 people who had been protesting outside Cairo’s Rabia al Adawiya Mosque marched toward the Republican Guard headquarters, where Morsi is rumored to have been held since being deposed by the military on Wednesday.
