I wouldn't pin much too hope on the AU delegation:

"Nabila Ramdani, a French journalist and Middle East expert, said the situation with regard to Libya had reached not only a military but also a political deadlock.

"It's quite worrying," she told Al Jazeera. "Unfortunately, my view about the African Union is that it will appear as not being a credible group of people to be in a position to broker a deal on behalf of Gaddafi.

"They are a group of dictators themselves and they won't be taken very seriously given that they're from very brutal regimes which are in many ways far worse than the Gaddafi regime."

Ahmad Bani, a rebel spokesman, rejected a negotiated outcome to the conflict.

"There is no other solution than the military solution, because this dictator's language is annihilation, and people who speak this language only understand this language," he told Al Jazeera."
