After six months of fierce fighting, Libyan opposition forces claim the conflict has reached a decisive phase.

The NATO-backed rebels are moving on the capital city of Tripoli and attempting to cut its supply lines. By doing so, they hope to put a stranglehold on Colonel Muammar Gaddafi's last bastion of power.

Yet even as they advance, rebel fighters and their leaders have different opinions about the future of Libya. As the struggle intensifies, so does the debate.
