If Gadhaffi's forces have indeed captured the oil city of Brega, they will now be able to cut off electricity to the rebel's stronghold of Benghazi where the final battle of this conflict is likely to take place. It's a very big city, and I expect the rebels have fortified it well, hoping to hold off Gadhaffi's forces long enough for someone to come and help them from outside.

The AFP news agency has reported that the Libyan armed forces loyal to Muammar Gaddafi have cleared "armed gangs" from the oil-rich town of Brega in the east, an army source told state television on Sunday.
"Brega has been cleansed of armed gangs," the military source was quoted as saying. The report could not immediately be verified. State television has in the past issued false reports claiming territory.
Chuck Schumer, a US democratic senator, has said that imposing a no fly zone on Libya "is more likely" because the Arab League supports the move.
Reuters news agency has reported that government troops advancing east along the coast road took Brega early on Sunday in what looked like an increasingly confident drive towards the rebel stronghold of Benghazi.
But the rebels, said they had re-taken Brega on Sunday night. There was no way of verifying the rival claims.
