JERUSALEM, Israel -- Egypt's Muslim Brotherhood threatened to resume rioting if the government doesn't "submit to the will of the people," the Egyptian newspaper al-Masry al-Youm reported in its English edition Wednesday.

Speaking at a conference organized by the Muslim Brotherhood in Alexandria, Hassan al-Brince said the "legitimacy" of the interim military government ends September 27.

Al-Brince accused the "remnants of the former [Mubarak] regime" of instigating chaos to delay elections and prolong their rule. He said members of Egypt's Muslim Brotherhood would be willing to risk their lives to accomplish their goals.

"We will not allow the U.S. and E.U. to enforce their agendas and homosexuality-promoting laws and the abolition of Islamic Sharia [law], as the people will not abandon Islam," al-Brince said.

Another speaker, Sobhi Saleh, told participants they would not "rest until the Islamic Sharia is fully applied."
