Will Obama ever support for the pro-democracy opposition? I’m guessing the answer to that question is, no.

CAIRO (AP) — Egyptian prosecutors on Monday summoned several opposition politicians and activists for questioning over allegations they incited violence against members of the president’s Muslim Brotherhood.

The summons came one day after the Islamist president sternly warned his opponents, saying he may be close to taking unspecified measures to “protect this nation.”

Angry, shouting and pounding the table at times, Mohammed Morsi vowed on Sunday to bring to account politicians found to have incited the violence on Friday, when Brotherhood members and protesters clashed outside the group’s Cairo headquarters.

Nearly 200 people were injured in the clashes, the worst violence between the Brotherhood and its opponents in more than three months.

Those summoned include former presidential candidate Khaled Ali, former lawmaker Ziad el-Oleimi and several iconic figures from the pro-democracy movement behind the 2011 uprising against Hosni Mubarak. These include Alaa Abdel-Fattah, Hazem Abdel-Azim, Nawara Negm, daughter of Egypt’s best known satirical poet, TV presenter Buthaina Kamel and senior opposition politician Mohammed Aboul-Ghar.
