Egypt's Parliament on Wednesday stripped two Muslim Brotherhood lawmakers of their immunity as parliament members, clearing the way for their arrests, a spokesman for the group said. The two, Sabri Amer and Ragab Abu Zeid, were briefly detained last month as part of an ongoing crackdown against the country's most powerful opposition group. They were not questioned by prosecutors while in detention and were released the following day. Twelve other members of the Islamic group were arrested with the two in the northern Nile Delta province of Menoufiya. They were ordered detained for 15 days, pending further investigation, accused of spreading Brotherhood propaganda. Under Egyptian law, lawmakers often enjoy immunity from prosecution unless the Parliament gives the clearance for a legal investigate.
