Throughout this time, the Daesh is attacking the Kobane pocket and has - according to Kurdish sources - reached a point only 5km outside this town, during the afternoon. And this after overrunning the local YPG HQ, as shown on this video (warning: GRAFFIC in some places!):

Coalition raids prompt ISIS advance on Syria Kurdish town
...ISIS has reinforced fighters who are battling Kurdish forces for control of a Syrian town at the border with Turkey, a redeployment triggered by U.S.-led air strikes on the group elsewhere, a Kurdish military official said.

Ocalan Iso, deputy leader of the Kurdish forces defending the town of Kobani at the Turkish border, said more ISIS fighters and tanks had arrived since the U.S.-led coalition began air strikes on the group on Tuesday.

"The number of their fighters has increased, the number of their tanks has increased since the bombardment of Raqqa," Iso told Reuters by telephone. He repeated calls for the U.S.-led coalition to expand its air strikes to ISIS positions near Kobani, which is also known as Ayn al-Arab.

"Kobani is in danger," he said.

So, the Kurds are crying for help, but all they've got so far is from the nearby pocket held by the FSyA (yes, there are two FSyA-held pockets north of Raqqa, no matter how much is this ignored by almost everybody), and from those Kurds that brought their families to the safety in Turkey, and then returned to fight the Daesh. Contrary to the extremists, though, neither the FSyA nor the YPG forces there have tanks and artillery: only RPGs and machine-guns.

Meanwhile, Twitter reports from this evening are indicating new waves of air strikes - but not in support of YPG/FSyA forces at Kobane: instead, those that 'know better' are blasting empty 'HQs' and 'storage sites' around Abu Kamal, Mayadin, and Markdah near Dayr az-Zawr...

This is making damn lots of sense. Especialy because the Daesh has withdrawn so many of its forces from this area, that its lines there are held by Arab tribes that used to fight for the FSyA already since 2011 (they nearly liberated all of Dayr az-Zawr in summer 2012), until they found themselves sandwiched between the regime and the Daesh (by the ISIS advance into their backs), then had all of their leaders killed by extremist suicide bombers - and were left without a choice but to submit themselves to the extremist command...

Congratulations to whoever is writing that frikkin' targeting list: this is reminding me of similar air strikes on Bagram AB back in October 2001, when somebody was so eager to spend several dozens of GBUs (the cheapest went at something like US$500.000) to blast rusty hulks of long-since abandoned MiG-15UTIs, MiG-17s and Il-28s at the local junkyard... while a look into one of old issues of the World Air Power Journal could've provided clear and undisputable evidence that such target selection is simply stupid.
