The Egyptian military stepped into the political crisis entering its third week Saturday with a notice that violence would not be allowed and urging the opposition parties to accept Egypt's President Mohamed Morsi’s call for national dialogue Saturday afternoon. Opposition leaders rejected the invitation, demanding that he first revoke his sweeping presidential decree and cancel the referendum on pro-Islamist draft constitution set for one week from today. Overnight, protesters broke through a security cordon into the presidential compound declaring they would stay there until their demands were met. Security police stood aside to avoid confronting them.
