CAIRO (AP) — Egypt remained on edge Sunday after security forces stormed a Cairo mosque a day earlier and the ousted president's Muslim Brotherhood remained poised to hold further street protests despite a possible outlawing of the group.
At one point, troops exchanged gunfire with men shooting from a minaret of the al-Fath mosque on Ramses Square, where hundreds of supporters of Mohammed Morsi had fled overnight after violent clashes killed 173 people.
The evacuation was prompted by fears that the Brotherhood again planned to set up a sit-in, security officials said, similar to those that were broken up Wednesday in assaults that killed hundreds of people.
Simultaneously, police arrested the brother of al-Qaida chief Ayman al-Zawahri, who officials said planned to bring in armed groups to provide support to those holed up inside the mosque.
