Cares less - they a re indiscriminately dropping iron dumb bombs - this seems to be because the the Syrian army, Hizballah and Shiite militias under Iranian command with Russian air cover have been unable to take Azaz on the Turkish boarder ... so they are going at Azaz by way of Idlib.
BTW: the US-Iranian-Russian-Iraqi offensive was launched to recover Ramadi from ISIS ... US and Russian army and air force elements, two varieties of Iraqi militia Shiites under Iranian command and Sunnis, the regular Iraqi army ... Iraqi army forces are attacking the Ramadi city center from the north; Shiite militias from the south. The US air force is pounding ISIS targets inside the town in order to cripple its ability to fight off the oncoming forces. The Russian air force is standing by, ready to destroy any ISIS reinforcements attempting to cross in from Syria to aid their comrades in beleaguered Ramadi.
However, ISIS has extensive underground tunnel systems which are not likely to be cleaned out
Do you have a source for all of that? I've been following alerts on Ramadi and everything I've seen clearly states it was 199% regular Iraq Army...not even militias. And they are at the center of town already, encountering fierce resistance.
