> A cautious welcome for US airstrikes on Cert. Libyan fighters besieging the Islamic State's stronghold, hoping the open-ended strikes that started on Monday could help them break through their defenses. Snipers and mines are for now holding back the anti-IS brigades, as Reuters Libya correspondent Aidan Lewis explains, from the northern city of Misrata.
>> The front lines in recent weeks have not moved that much. But the Libyan forces are still making some progress, and they'll hope that that progress can accelerate now that they have support from US airstrikes. The brigades are very gradually now trying to advance into the positions that Islamic State still holds, some of which are in big buildings,
e conference center, the hospital, the university.
Some in residential neighborhoods, where there's been house-to-house street fighting. And they're using snipers and mines to defend their positions. And that's something that the Libyan forces have found very difficult to deal with, and one of the reasons why, so far, they've welcomed the US intervention with airstrikes. Because they hope that that will allow them to break down these defenses.
I think that Libya won't become a big focus regionally for Islamic State, because I think that the forces who are trying to push Islamic State out of Cert will eventually succeed. Now, Islamic State might still be a threat in Libya. It's thought that at least some of their senior commanders have escaped during the early stages of the battle.
But if they lose Cert, they will no longer hold any territory in Libya. That'll be a huge blow for them.
