JERUSALEM, Israel -- Turmoil continues to build in Egypt and Syria as mass protests forced Islamist President Mohammed Morsi to leave his palace in Cairo.

Many Egyptians are angry over Morsi's seizure of power and hastily written draft constitution that would enshrine Islamic Sharia law.

"Egyptians had a peaceful revolution and today we're demanding that one party doesn't control everything. The revolution is for all the Egyptian people, but now one party is trying to control everything and that's what we reject," Taher Abu-Zeid, one of the protestors, said.

Morsi reportedly left the palace through a back door after the demonstrations grew larger and turned violent, but he returned the next day.

Meanwhile in Syria, amateur video emerged on Tuesday showing fighting in the capital, Damascus.

More than 40,000 people have been killed as President Bashar Assad's forces have attempted to crush an uprising-turned-civil war.

New fears arose in the international community this week that Assad might use stockpiles of chemical weapons against the rebels.

Reports indicated Israel might participate in a U.S.-led coalition to attack those chemical weapons.

Israel shares a border with Syria on the Golan Heights. Israeli officials have said they would act to stop Syria's huge chemical weapons stockpile from falling into the hands of terrorists.

Israeli Prime Minister Benjamin Netanyahu said he's standing with the United States.

"Together with the international community, we are following developments in Syria regarding their stockpile of chemical weapons," Netanyahu said.

"I heard the important things that President Obama said in this matter [and] we are of the same opinion -- that these weapons should not be used and must not reach terror groups," he said.

U.S. officials said earlier that the White House and its allies are considering military options to secure Syria's chemical and biological weapons cache.
