CAIRO (AP) – Protesters have again turned out in the tens of thousands in Egypt today to denounce President Mohammed Morsi and the draft constitution that his Islamist allies approved early today.

It was approved in a rushed, all-night session without the participation of liberals and Christians.

This is the second major protest since Morsi issued decrees a week ago granting himself wide-ranging powers. Crowds marched from several locations in Cairo, converging in central Tahrir Square. They chanted that the constitution is “void,” and that “the people want to bring down the regime.”

The Muslim Brotherhood and other supporters of Morsi are planning their own massive rally tomorrow.

The anger at Morsi even spilled over into a mosque where the Islamist president today joined weekly Friday prayers. In his sermon, the mosque’s preacher compared Morsi to the Prophet Mohammad, saying the prophet had enjoyed vast powers as a leader, and that it set a precedent for the same thing to happen now.

Worshippers interrupted him, shouting, “No to tyranny!” Morsi himself took to the podium and said that he also objected to the language used by the sheik. Morsi said one-man rule contradicts Islam.
