Radical Islamists took over a Cairo mosque and used it to torture Christians who had been protesting against the Muslim Brotherhood, CBN News reports. According to Fox News, mosque officials were so upset over the incident that they had filed a police report. Leaders of Bilal Ibn Rabah mosque said radicals took control of the building after Friday prayers, then detained Christian and Muslim protesters and tortured them there for hours. Mosque officials said they "deeply regret what has happened and apologize." Observers say that more radical elements of the Muslim Brotherhood are gaining power in Egypt and pushing an Islamist agenda.
