After Libyan rebels took Zlitan, Zawiyah, and Gharyan, effectively encircling and cutting off Tripoli, an uprising broke out in Tripoli. Opposition groups in Tripoli, mostly quiet since Qaddafi's brutal crackdown in February and March, launched an uprising codenamed "Mermaid Dawn." At the same time, the Libyan rebels who have made rapid advances over the last two weeks to bring them to Tripoli's doorstep have pushed into Tripoli itself. Qaddafi's grip over Tripoli, at least, seems to be nearly broken. It remains to be seen whether Sirte, Qaddafi's hometown, and its environs will fall easily in the wake of Qaddafi's ouster from Tripoli or whether it will remain a redoubt of pro-Qaddafi support.
