Cairo (CNN) -- Fighting erupted Friday across Egypt between hundreds of supporters of Mohamed Morsy and their opponents, leaving nearly two dozen people dead and hundreds more injured while raising fears of widening violence after the military ousted the country's first democratically elected president.
The violence came as Morsy's supporters held massive protests across the country, calling for his reinstatement, a counter to huge demonstrations among those celebrating his ouster.
At least 22 people were killed Friday and more than 500 were injured in clashes across the country that at times pitted Morsy supporters against his opponents and the military, state-run Egyptian television reported, citing the Ministry of Health.
