Libyan gunmen surround the Libyan Justice Ministry demanding a ban against those who worked under the former regime of ousted leader Gaddafi from holding senior positions on April 30, 2013, in the capital Tripoli. Gunmen have said their siege of the ministries would be lifted when their demands are met by a vote in the General National Congress — Libya's highest political authority — on a bill calling for the expulsion of former regime employees.
