SIRTE, LIBYA – Although Libyans are now celebrating the first anniversary of the revolution that toppled Muammar el-Qaddafi, they are increasingly frustrated with their new leaders. Libyans complain that the interim government, known as the National Transitional Council (NTC), has not moved quickly enough to purge and prosecute senior Qaddafi officials, or to rein in the militias that overthrew his regime.
