Al Jazeera's James Bays reports with the latest from the eastern rebel-held town of Tobruk:
There have been fresh air strikes we understand in the last few minutes in Benghazi. One of those airstrikes, another one, taking place on the main airport there. And we're hearing this time from our team that were there ... that there have been casualties this time.
"The opposition are claiming that they've made some successes as well, they're claiming that they've shot down a MiG aircraft. I have to say that our correspondent Tony Birtley has been to the scene where this MiG aircraft is supposed to have been shot down, and he can find no sign of it at all."
Asked about the situation in Tobruk, he said:
It is a long way away, but I think they are still concerned, and they're concerned because Gaddafi's forces in the last few days have been pounding Ajdabiyah. Now that is the gateway to Benghazi, but it's also the gateway to Tobruk, because there's another road that goes through the desert that goes ... to here. And there is some suggestion that possibly one of the things that Gaddafi might consider is to try and seal off the whole of this peninsula by taking that road. Not actually going into Benghazi, but sealing off Benghazi and the other cities along the coast and possibly even closing the border.
"I spoke a short time ago to a Major-General who has come back from the front line, and he says that ... they are prepared in Benghazi, but they're also prepared here, because they know that that is one possible option of Gaddafi to send forces this way and then to try and encircle all of the rebel troops.
"There's a very defiant mood here, and a lot of support for those opposed to Gaddafi. But you go out on the streets, you go to the edge of town ... and really no evidence of any defences at all that I could see, right at the edge of the town in the last few hours, we went out there to the airport, which is on the very edge of the town, that's the way Gaddafi's forces would come if they came all the way to Tobruk. And there were just a few fighters, one of them couldn't have been more than about 12 years old ... so not strong defences.
"And I can tell you that when you speak to the people here, they say they're winning, they say they're beating back Gaddafi. Then you ask them the question should the international community do more, and they say 'Yes, we're all going to die if they don't help'. So very contradictory answers to those questions.
