On 7 December, Morsi supporters and anti-Morsi demonstrators continued their protests in different cities including Cairo, Alexandria, and Assiut. Demonstrators in Assiut chanted "No Brotherhood, no Salafis, Egypt is a civic state."[298] Dozens of protesters threw rocks and glass bottles at Morsi's home in Sharkia province and tried to push aside a police barrier.[299] Advisers and Brotherhood leaders acknowledged that outside his core base of Islamist supporters Morsi felt increasingly isolated in the political arena and even within his own government.[300] Opposition leaders said in a statement that Morsi's 6 December dialogue offer failed to meet "the principles of real and serious negotiations" and displayed "the complete disregard" for the opposition's demands. They said they would not negotiate with Morsi until he canceled his 22 November decree and called off the 15 December referendum on the draft constitution.[301][302][303] Opposition protesters marched on the presidential palace and breached a security perimeter built by the military's elite Republican Guard – charged with protecting the palace – which withdrew behind the palace walls.[301][302][303] The Egyptian newspaper Al-Masry Al-Youm also reported that individuals suspected of protesting against the Muslim Brotherhood were being tortured and beaten in a facility run by the Brotherhood in Heliopolis, a Cairo suburb.[304]
