"The Russian Air Force has caught the so called “Islamic State of Iraq and Al-Sham” (ISIS) off-guard in east Hama, striking their main supply route from the Al-Raqqa Governorate to the ancient city of Palmyra (Tadmur) on a number of occasions today. However, the latest airstrike by the Russian Air Force has proven to be the most lethal, destroying an entire ISIS convoy of reinforcements that were tasked to back-up their exhausted fighters at the Palmyra front in the eastern countryside of Homs. According to a military source, the Russian Air Force caught the ISIS convoy attempting to make their way from the large village of ‘Aqayrbat in east Homs to the city of Palmyra." AMN
Well, this piece speaks of repeated Russian strikes against IS efforts to reinforce in the Tadmur (Palmyra) area against the Syrian Army's advance spearheaded by the Tiger Forces brigade.
Once again, IMO the wheels are coming off the IS wagon in Syria and Iraq. The question does not seem to be whether Raqqa will be lost by IS but rather when and to whom. pl
