There are so many conflicting stories that it is impossible to know what is going on from afar. It is possible that the Colonel's ceasefire announcement combined with the further talks in Paris to-day has given Government Forces the time needed to close to or within Benghazi.

It would also mean he does not now need to use his Air Force. How do we then use Air Power alone to get him to withdraw especially if he then has his supporters around or on the roofs of potential targets? And all on live TV!
