An Egyptian riot policeman detains a female student of al-Azhar University during a protest by students who support the Muslim Brotherhood inside their campus in Cairo on December 30, 2013. Egypt urged Arab League members to enforce a counter terrorism treaty that would block funding and support for the Muslim Brotherhood after Cairo designated it as "terrorist" group.
