Egypt's call to disband protests by the Muslim Brotherhood movement "will trigger chaos," the Islamist extremist group Jamaa al Islamiya warned Thursday. The country's interim rules have pledged to take all "necessary measures" to deal with sit-ins, claiming they pose a threat to the country's national security. The Egyptian military installed the interim government after it overthrew elected President Mohammed Morsi on July 3. The Muslim Brotherhood protests have been continuing since then. Plenty of bloodshed has accompanied the protests, as protesters have clashed with security services. At least 100 people were killed on Saturday alone. The extremist group is known for the 1997 Luxor tourist massacre, but has since renounced violence.
