Many of the injuries were from metal rods smashing faces and from bricks and rocks, said Dr Mona Mina, who is working at the clinic in the nearby Omar Makram mosque.
The casualty toll, higher than that provided by the health ministry, includes many light injuries, she added.
The satellite channel Al Arabiya earlier quoted Health Minister Ahmed Farid as saying three people had been killed in the clashes and his ministry said 611 people were injured. (*)
