On the map, you can see how they have captured their way into the suburbs of Tripoli bit by bit.
I am not saying that there are huge changes, but they capture a few blocks every now and then. This is problematic as they are very close to the city itself.
They have been very close to the city since now 1 year actually but it looks more and more costly as far as I can tell to fight that war especially as the sand money dries up from their emirati camel riders.
