Egyptian riot police have fired teargas at protesters demonstrating against President Mohamed Morsi near the presidential palace in Cairo. Ten people have been injured in clashes, Al Arabiya reports.

Protesters have broken through police lines in front of the presidential palace.

Presidential sources say Morsi has left the palace as clashes continue outside.

Thousands of demonstrators marched to the palace in protest of Morsi's decree which grants him near absolute powers, and a draft constitution which was quickly adopted by his allies.

The march came as no surprise – earlier on Tuesday, demonstrators warned they would approach the palace if action was not taken. 

"This is the last warning before we lay siege on the presidential palace," 21-year-old protester Mahmoud Hashim told AP. "We want the presidential decrees cancelled."

A crowd of several hundred protesters also gathered outside a mosque in the Abbasiyah district earlier in the day shouting, "Freedom or we die! Mohammed Morsi! Illegitimate! Brotherhood! Illegitimate!"

Demonstrators assembled in front of Morsi's residence shouting, "Down with the sons of dogs. We are the power and we are the people!"

Morsi has called for a nationwide referendum on the draft constitution on December 15.
