Egyptian authorities have detained eight members of the banned Muslim Brotherhood bringing to 30 the number seized in roundups that began last month, police and the group said.
Brotherhood leaders accused the government of carrying out the arrests in retaliation for criticisms made by the group's members of parliament. The banned but tolerated organization won nearly 20 percent of the legislature's seats in last year's elections, making it the largest opposition bloc.
The eight men, including senior figures, were arrested Friday evening in the Mediterranean coast city of Alexandria, the group's web site said.
Detainees include Helmi el-Gazzar, a local leader in Cairo who was picked up during a wave of demonstrations last year and jailed for five months, and Hassan el-Prince, a medical professor in Alexandria.
