As the government proposes legal dissolution of the group, we ask if it will be forced to go back underground.
After days of violence, Egypt's leaders are toughening their rhetoric against the Muslim Brotherhood.
Hazem el-Beblawi, Egypt's interim prime minister, has proposed the legal dissolution of the Brotherhood.
"We're not into the effort of dissolving anyone - or preventing anyone from being active in the public domain, but we're trying to make sure that everyone is legalised according to what the Egyptian law says ...." Mostafa Hegazy, a spokesperson for Egypt's interim president, said.
If the Brotherhood is dissolved, it will be forced to go back underground, and many fear that it may even embark on a path of armed resistance.
