Egypt's liberal opposition leader, Mohamed El Baradei, is calling for a broad national dialogue with the Islamist government, all political factions, and the powerful military.
El Baradei, a Nobel Peace Prize winner, is making the appeal a day after the nation's defense minister warned the country could collapse under the weight of protests against Egypt's President Mohammed Morsi.
On Wednesday, protestors clashed with riot police in Cairo for a seventh day. The rioters threw stones and petrol bombs at police who responded with tear gas.
The demonstrators are calling for the ouster of Morsi and have virtually declared a revolt against his rule.
Morsi has declared a state of emergency and night curfew in three provinces along the Suez Canal, although residents have defied the curfew. He will makes a brief visit to Germany Wednesday in the midst of controversial comments made by a staffer about the Holocaust.
A top aide to Morsi said U.S. intelligence agencies fabricated the Holocaust in order to ruin Germany's public image during World War II. In a report on Fox News, aide Fathi Shihab-Eddim said the reported 6 million Jews killed by the Nazis moved to the United States.
"The myth of the Holocaust is an industry that America invented," he said "U.S. intelligence agencies in cooperation with their counterparts in allied nations during World War II created it to destroy the image of their opponents in Germany, and to justify war and massive destruction against military and civilian facilities of the Axis powers, and especially to hit Hiroshima and Nagasaki with the atomic bomb."
