By ReutersCAIRO -- Egyptian police fired tear gas at protesters demonstrating against President Mohamed Morsi's drive to hold a snap referendum on a new constitution and some broke through police lines around his palace, live television footage showed.
Several thousand protesters had gathered nearby in what they dubbed "last warning" protests against Morsi, who has angered opponents with a November 22 decree that expanded his powers.
"The people want the downfall of the regime," chanted the protesters.
Morsi ignited a storm of unrest in his bid to prevent a judiciary still packed with appointees of ousted predecessor Hosni Mubarak from derailing a troubled political transition.
