Meredith Birkett says: On Twitter, Nevine Zaki linked to a picture she said she photographed on Wednesday of Christians protecting Muslims during their prayers in Tahrir Square. The square in Cario continues to be a scene of violence between pro- and anti-Mubarak supporters who were wielding sticks and throwing rocks. She tweeted:
