BTW, some more news:
http://www.bbc.com/news/world-middle-east-35906568
'Syrian government forces have re-captured the ancient city of Palmyra from so-called Islamic State (IS), say state media and a monitoring group.
The Syrian army had been gaining ground for several days, supported by Russian air strikes. Military sources say the army now has "full control".'

So does Russia fight ISIS or not, make up your mind, guys???
