Egypt's banned Muslim Brotherhood says police have arrested 21 of its members, including a former lawmaker. A statement posted Thursday on the group's Web site says the men were arrested while meeting the previous night at the Cairo home of former lawmaker Abdel Hamid el-Seyed. The Brotherhood is Egypt's largest opposition group. Though officially banned, members have run for political office as independents, and they currently hold about a fifth of the seats in Egypt's parliament. The government has carried out a steady campaign of arrests against the group, with more than 800 members detained so far this year.
