By night, Cairo's streets were filled with smoke and flames…and fire balls hurled by protesters --- many of them furious with the Muslim Brotherhood, the party of President Mohammed Mursi.
At least forty people were injured in the clashes outside the Islamist organization's headquarters. The unrest began earlier in the day after demonstrators set fire to the group's buses
While protests have dwindled since last year, the country is still deeply divided over the direction the country is headed in.
Restoring law and order has been a challenge and anger is close the surface. This month, clashes in Port Said, turned deadly. The turmoil is hurting the president's efforts to revive the economy and bring in investors.
