Protests Turn Violent in Cairo

And not because nobody can agree on the spelling of Mursi's name

Clashes erupted in Cairo on Friday after Egyptian political forces called on President Mohamed Morsy to take a stand for justice after his first 100 days in office.

Shops and streets at Tahrir Square were closed as Morsy supporters and critics threw rocks at one another. At least 110 people were injured, state-run Nile TV reported, citing health ministry officials.

Thousands turned out for the protest, with some groups chanting, "Leave Morsy." Protesters threw Molotov cocktails at one another, and firecrackers sounded amid clashes around Tahrir and Talat Harb squares.
